P2P Optimization Operation Strategy for Photovoltaic Virtual Power Plant Based on Asymmetric Nash Negotiation

Under the guidance of the “dual-carbon” target, the utilization of and demand for renewable energy have been growing rapidly. In order to achieve the complementary advantages of renewable energy in virtual power plants with different load characteristics and improve the rate of consumption, an interactive operation strategy for virtual power plants based on asymmetric Nash negotiation is proposed. Firstly, the photovoltaic virtual power plant is proposed to establish the optimal scheduling model for the operation of the virtual power plant, and then the asymmetric Nash negotiation method is adopted to achieve the fair distribution of benefits. Finally, the ADMM distribution is used to solve the proposed model in the solution algorithm. The simulation results show that the revenue enhancement rates are 28.27%, 1.09%, and 12.37%, respectively. The participating subjects’ revenues are effectively enhanced through P2P power sharing. Each subject can obtain a fair distribution of benefits according to the size of its power contribution, which effectively improves the enthusiasm of the PV virtual power plant to participate in P2P interactions and thus promotes the development and consumption of renewable energy.

The role of peer-to-peer interactions in sharing accommodation: From cocreation experience to peer customer engagement

Taking a service-dominant logic, the sharing accommodation business model consists of two forms of value cocreation: experience cocreation during the accommodation service and peer engagement behaviors after its end. Experience cocreation based on peer-to-peer interactions (P2P interactions) is the key to unlocking the competitive advantage of sharing accommodation. However, the understanding of P2P interactions and how they influence peer engagement behaviors is still limited. We systematically deconstruct P2P interactions and explore their impact on peer engagement behaviors using a dataset of 13217 reviews, a correlated topic model analysis method, and a linear mixed-effects model. Our results show that interpersonal interactions (relationship-oriented social interactions and transaction-oriented functional interactions) have a stronger positive effect on peer engagement behaviors than the physical environment. Social interactions and the physical environment have substitution effects on the impact of peer engagement behaviors. Furthermore, offline interactions positively moderate the impact of P2P interpersonal interactions on peer engagement behaviors.

State and Challenges for the Development of Cooperation in Science and Technology between Russia and China

Purpose: the main purpose of this article is to analyze the state and prospects of science and technology (S&T) cooperation between the Russian Federation and the PRC in the context of the global S&T cooperation trends.Methods: research is based on a combination of desk and field methods. The article is based on the data from official documents of the Russian Federation, state companies, institutions for development, and other structures, as well as media sources. A series of non-focused expert interviews with representatives of the innovation and expert community, linked to Russia-China S&T cooperation, was also conducted.Results: the main trends and directions of the S&T cooperation between Russia and China in 2000–2020s have been identified, including: large projects in traditional medium- and high-tech industries; horizontal academic cooperation; bilateral activities in developing innovation infrastructure (science parks, investment funds, etc.); tech activities of big corporations – with special focus on Huawei. Several factors, limiting the potential of bilateral S&T cooperation, were identified. Among the most important are: differences in the structure of real (not declarative) S&T priorities; weak complementarity of both economies and unwillingness to form harmonized trade and investment regimes (also because of the different size of Russian and Chinese economies); the techno-nationalist ideology of state policies of both nations; mismatching areas of scientific leadership that impedes synergy in academic research. The fragmentation and insufficient financial support of the Russian S&T and innovation sectors are noted as separate factors.Conclusions and Relevance: despite high mutual interest in intensification of Russia-China dialogue is declared, there are clear limits for bilateral S&T cooperation. Existing restrictions predetermines the preservation of a relatively small scale of S&T cooperation for the foreseeable future, with P2P interactions of groups of actors at its core. However, some of these interactions may be large-scale and long-term, as is the case of Huawei. One of the ways to change this dynamic (not saying about urgent need to optimize economic situation in Russia) is to develop a comprehensive strategy of cooperation with China – with subsequent focus on a small group of most important initiatives and creating favorable conditions for interaction of private and academic actors.

An integrated P2P framework for E-learning.

The focus of this paper is to design and develop a Peer-to-Peer Presentation System (P2P-PS) that supports E-learning through live media streaming coupled with a P2P shared whiteboard. The participants use the “ask doubt” feature to raise and resolve doubts during a session of ongoing presentation. The proposed P2P-PS system preserves causality between ask doubt and its resolution while disseminating them to all the participants. A buffered approach is employed to enhance the performance of P2P shared whiteboard, which may be used either in tandem with live media streaming or in standalone mode. The proposed system further extends P2P interactions on stored contents (files) built on top of a P2P file sharing and searching module with additional features. The added features allow the creation of mash-up presentations with annotations, posts, comments on audio, video, and PDF files as well as a discussion forum. We have implemented the P2P file sharing and searching system on the de Bruijn graph-based overlay for low latency. Extensive experiments were carried out on Emulab to validate the P2P-PS system using 200 physical nodes.

Effects of User Interactions and Community Self-Government Management on Creative Output in Firm-Hosted Innovation Communities: A Cross-Level Empirical Analysis

Innovation communities are being deployed increasingly by firms to gather ideas from users to sustain their competitive advantage. As one of the representative characteristics of innovation communities, effective interaction has always been perceived as a prerequisite for new product development. To investigate the inherent creative output logic, this article proposes a theoretical model to delineate the relationships among users’ online interactions [peer-to-peer (P2P) and peer-to-firm (P2F)], community self-government management (CSM, which refers to a style of management that admits users not only as participators but also as governors in the community), and creative output quantity (/quality) of new products. This model is validated empirically using data of 2000 sample users crawled from 20 firm-hosted innovation communities and 80 survey data from community administrators. The findings reveal the significant effects of users’ P2P and P2F interactions on the creative output quality and quantity as well as the moderating role of CSM. These findings suggest implications for how firms manage innovation communities and cultivate user interactions with peers and firms to capture the wisdom of the crowd.

Peer-to-peer interactions for better customer experience

Background: Firms have yet to harness the resulting connections from peer-to-peer (P2P) interactions to positively influence and deliver transformative customer outcomes. This research is a qualitative case study to investigate how a firm in public healthcare improved wellness and overall well-being of community-dwelling seniors. The study proposed a decentralised, disintermediated and democratised governance model, for firms to manage P2P interactions. Method: The investigator used an ethnographic study to gather contextual insights into the motivations, behaviours, experiences and outcomes of P2P participants and a firm’s actors. The focal firm, a public healthcare organisation, operated three wellness and activity centres (“Centres”) for community-dwelling seniors. These Centres aimed to promote supported self-management communities and reduce incidences of frequent hospital admissions. A three-part iterative analytical technique was used to analyse data from in-depth interviews with thirty-nine respondents and site observations. Results: Through frequent interactions and participation at the Centres, there was a sense of community among member residents. Each of the twenty-nine resident respondents, average aged 66, reported a sense of purpose from leading and participating in activities at the Centres. The Centre managers facilitated P2P interactions by pairing residents to help one another. They developed communal norms to regulate P2P interactions. Example, a mainstay at all Centres was the daily morning exercises regardless of mobility status. The residents interviewed expressed improved control over their chronic conditions and reported positive experience overall. The data gathered supported the proposition: a strong sense of community was related to increased community engagement which associated with positive customer experience. Conclusion: Unlike a physician-centric healthcare model where patients were passive recipients, the firm drew on the participation of community-dwelling seniors to manage the customer experience. The focal firm adopted a model that was decentralised, democratised and disintermediated, to shape P2P interactions wherein the member residents became proactive co-creators of value instead of mere recipients. This study contributed to the body of work in transformative service research. Although limited by external validity, the findings offered associations of the constructs like community engagement and self-efficacy. Future research could evaluate the sustained impact on well-being at different levels – individual, community, and population.

Peer-to-peer interactions: Perspectives of Airbnb guests and hosts

In peer-to-peer (P2P) accommodation settings such as Airbnb, social interactions between peers are distinctively different from those between guests and employees in conventional lodging establishments. This study focuses on a reciprocal aspect of social interactions in P2P accommodations and aims to: 1) explore how guests and hosts perceive online and face-to-face interactions between them and 2) investigate the association between P2P interactions and some outcome variables (encounter satisfaction, word-of-mouth intention, and continuous intention to use) based on the roles of guest and host. A total of 503 responses from an online research panel were analyzed. The results show that guests perceive overall interaction experiences more positively than do hosts. Moreover, guests and hosts place weight on different interaction factors that contribute to their satisfaction and behavioral intentions. This study sheds light on the reciprocal interactions between guests and hosts, providing important theoretical and practical implications for the P2P lodging experience.

Fostering Customer Ideation in Crowdsourcing Community: The Role of Peer-to-peer and Peer-to-firm Interactions

Firms increasingly engage customers in idea generation (or ideation) to sustain their competitive advantages. Drawing from social interaction literature, this study adopts a social network perspective to investigate empirically how the characteristics (i.e., direction, size, and strength) of customers' online peer-to-peer (P2P) and peer-to-firm (P2F) interactions, moderated by customers' past efforts to post ideas (i.e., past ideation participation), influence their likelihood of generating ideas in an idea crowdsourcing community. With four years of data from a popular online crowdsourcing site, this study demonstrates the significant impacts of P2P and P2F online interactions on customers' likelihood of subsequent idea generation. In particular, a potential double-edged sword of past ideation participation emerges: A high level of past ideation participation strengthens (weakens) the impact of P2F (P2P) interactions on customers' subsequent idea generation. These findings suggest implications for how firms can cultivate customers' online social interactions with peers and firms and enhance their capabilities for capturing the wisdom of the crowd.

Protection of LAN-wide, P2P interactions: a holistic approach

This article advocates the need of a holistic approach to protect LAN interactions and presents a solution for implementing it based on secure LAN (SLAN), a novel security architecture. SLAN uses the 802.1X access control mechanisms and is supported by a key distribution centre (KDC) built upon an 802.1X authentication server. The KDC is used, together with a new host identification policy and modified DHCP servers, to provide proper resource allocation and message authentication in DHCP transactions. The KDC is used to authenticate ARP transactions and to distribute session keys to pairs of LAN hosts, allowing them to set up arbitrary, LAN-wide peer-to-peer security associations using such session keys. We show how PPPoE and IPSec security associations may be instantiated and present a prototype implementation for IPSec.

Development tools for open agent networks

Distributed peer-to-peer computing in which no centralized control server is assumed, and in some cases, client-server architecture is actually rejected, has been the subject of intense investigations in the field of information technologies in the recent years. This new paradigm of designing large-scale distributed intelligent systems attracts attention of both researchers and developers of industrial applications. This paradigm provides qualitatively new capabilities, especially for designing systems consisting of a large number of autonomous instances which can appear and disappear from the system at any time instant. The idea of integration of these systems (hereinafter, P2P systems for brevity) and multi-agent technologies is especially attractive; it realizes the advantages of both paradigms, namely, the maturity of technologies and the relative simplicity of creation of multi-agent systems consisting of autonomous intelligent programs which interact via a high-level language, as well as the openness, the scalability, and the reliability of P2P systems. This integration seems quite natural. Indeed, multi-agent systems is the set of autonomous intelligent programs; therefore, the structuring of these programs into the network whose nodes interact directly without any intermediate server is the natural step if the technology of P2P interactions has been well developed using a high level language. However, for practical realization of this idea, it is necessary to make one very important step, namely, to develop mechanisms for agent interaction on a semantic level, when agents query some functionalities (services) from each other, possibly, not knowing a priori what particular agents can provide the queried functionality (service) and whether these agents exist in the network. The application of the agent variant of the architecture, the service oriented architecture, another new paradigm of construction of information systems, provides practical capability of realization of mechanisms of semantic interaction of agents of the open P2P network. This work represents the P2P agent platform developed by the authors whose instances installed on the network nodes above the standard P2P service form the distributed meta-knowledge knowledge base intended for organization of semantic P2P interaction of agents. Application-oriented agents placed on the network nodes above the instances of the agent platform receive the capability of semantic interaction. The program realization of the platform is supported by the mechanism of P2P interaction of agents using messages with standard formats and pair communications of the network nodes. The role, functions, and the essence of the processes of operation of this platform is explained using two applications as the examples; these applications are sufficiently important from the practical point of view. They are used for verification of basic solutions presented in this work.

Towards enabling peer‐to‐peer Grids

AbstractIn this paper we propose a peer‐to‐peer (P2P) Grid comprising resources such as relatively static clients, high‐end resources and a dynamic collection of multiple P2P subsystems. We investigate the architecture of the messaging and event service that will support such a hybrid environment. We designed a distributed publish–subscribe system NaradaBrokering for XML‐specified messages. NaradaBrokering provides support for centralized, distributed and P2P (via JXTA) interactions. Here we investigate and present our strategy for the integration of JXTA into NaradaBrokering. The resultant system naturally scales with multiple Peer Groups linked by NaradaBrokering.
