THE ROLE OF THE 20HYGRID PROJECT AND GAS DISTRIBUTION INFRASTRUCTURE IN ROMANIA'S ENERGY TRANSITION

20HyGrid is the first blending pilot project developed in Romania, in the context of the climate neutrality strategy. The project aimed to verify the compatibility of current distribution networks, of house installations/ appliances using a mixture of natural gas and 20vol.% hydrogen, noxious reduction and collaboration with authorities for developing legislative framework for green gases distribution through the current natural gas infrastructure. The tests analyzed both the functioning of existing appliances and burning/combustion process. No technical risk was identified when operating with this mixture (without appliances modifications). The significant reduction of emissions confirms the results of similar European projects. Romanian gas infrastructure is a key component of energy transition.

Editorial

Enter any contemporary art museum, gallery, or biennale in 2024 and chances are that the live arts will be center “stage.” While theater, dance, music, and performance art were historically presented in visual arts contexts as fringe or one-off events, since the turn of the twenty-first century—and gaining momentum over the past decade—there has been a growing tendency to “exhibit” live art. As choreographers, directors, and composers who have built their careers in the visual art world—which is significantly more monied than the performing arts world—take home major prizes and awards, leading museums are inaugurating spaces designed exclusively to house installation and performance. But architectural spaces are also ideological spaces with tacit value systems that influence conventions of performance and spectatorship, as well as perceptual experience. What happens when live arts are transplanted into the modernist project of the white cube, characterized as it is by its putative neutrality, objectivity, universality, disembodiment, and erasure of context (see O'Doherty [1976] 1999)? Today's eventized museum showcases works of art characterized by durationality (they are circumscribed by time), corporeality (they feature live, gesturing bodies), and relationality (they foreground the intersubjective exchange) that engender new modes of what Nicolas Bourriaud (2002) called “relational aesthetics.” In so doing, these works challenge traditional definitions of the “collection,” the “archive,” the “museum,” and even “contemporary art.”

Installation of solar power plant in Adıyaman region and analysis of solar energy potential

Energy is one of the most necessary and fundamental needs for human beings to continue their lives. Solar energy, which is one of the most important renewable energy sources, has great energy potential in our country with its long radiation duration and radiation amount.
 The primary thing to do in solar power plant (SPP) installation is to analyze the climatic characteristics of the region. Therefore, having and analyzing the meteorological data of the region has important advantages for the solar power plant to be established. The importance of solar radiation data in the installation of a solar power plant in a region is directly proportional to the payback period of the plant under normal conditions. In this study, a 1 MW SPP feasibility study was conducted in Besni district of Adıyaman province. Depending on the energy potential of the regions, it is calculated that the payback period is between 2-5.7 years for Adıyaman province. Considering the state's electricity pricing, it is seen that the payback period in the industry is about 2 years, while it has a period of 5.7 years for house installation.
 SPP is analyzed in the light of solar radiation data in the Adıyaman region which will be a pioneer for future studies thanks to the depreciation period as well as analyses performed. In addition to these, the parameters to be considered during the SPP installation stages will be specified in detail.

AI 스마트 하우징 구축이 서울시 아파트 거래가격에 미치는 영향

The AI smart housing market is expected to grow, but there is no study on the effect of the installation of AI smart housing on housing prices in terms of activation. It was attempted to demonstrate whether there is a housing price as a characteristic of a house through the hedonic model, which is most commonly used.
 The empirical data was used by combining the K-apt apartment management fee disclosure data and the apartment price and apartment characteristics data provided by Real Estate 114 Reps. According to the apartment management cost information provided by K-apt, 2,144 (12.15%) of 17,638 apartment complexes nationwide for which the AI Smart Housing maintenance fee is charged as an AI Smart Housing were installed. In the case of Seoul, an AI Smart Housing was installed in 213 (8.59%) of the total 2,479 apartment complexes.
 As a result of attaching price information to the management cost information, a total of 12,073 apartment transaction price data were used, and 1,598 pieces of AI Smart Housing installation complexes were used for the analysis. As a result of the empirical analysis, as in the general hedonic model, the house sale price per unit area was higher as the transaction level increased, the number of years elapsed, the total number of households, and the common management cost per household increased. In the case of common management fees, in the case of apartments that are recently supplied, the common management fees are high according to the trend of supplying various resident convenience facilities such as swimming pools and golf driving ranges in the complex, as well as large lobby spaces, and this can be seen as a result of this part being reflected in the house sale price. . In addition, the fact that the smaller the exclusive area is, the higher the price per unit area is due to the fact that the preference for small flats due to the downsizing of the household size, such as the increase in one- or two-person households, is reflected. Lastly, it was found that the apartment price per unit area was higher when the AI Smart Housing, the subject of this study's interest, was installed, compared to the case where the AI Smart Housing was not installed.

Algorithm for optimizing the lifetime of solar batteries and the energy consumption of a smart house

The increase in energy demand as well as the problems related to the environment are two main factors that push developing countries to focus their interest on the smart house. Their installation will allow to reduce greenhouse gas emissions, fight against global warming and save energy. Indeed, a smart grid must be instrumental in both setting up a good management of the decentralized production which provides a reliable electrical supply, and in organizing the storage of energy in batteries which are the weak point of a smart house installation. The modeled and simulated system represents the most reliable management method, using an algorithm that will improve the photovoltaic production, to minimize the use of the public grid in order to reduce the energy cost. This algorithm decreases the charge/discharge cycle of the battery, and increases their longevity. The coming further researches would allow the identification of useful parameters that increase the lifetime of solar batteries in order to solve the current smart house problem.

High PV Penetration Impact on European-based LV Residential Network

The impact of high PV penetration into the grid particularly at the distribution side has been extensively studied. However, most of the available research focuses on North American style systems. This project aims to investigate the effect of high PV penetration at a residential area in a European-based distribution network, which is electricity supply system Malaysia is based on. The modeling is done using OpenDSS while the network model used is the IEEE European Low Voltage Test Feeder which consists of 55 loads representing a generic housing area. Each load point is then equipped with a 4 kW PV system-representing a typical size for a house installation. PV output variability is then introduced into the modeling using two sample days of actual irradiance variability obtained from UTeM Malaysia; one for clear day and another for a high variability day. Voltage unbalance, voltage rise and reverse power flow were analyzed. One significant finding of this project is that voltage rise exceeds the standard of 1.05 pu during noon. Besides that, the high variability days significantly affect the mitigation measures required to manage reverse power flow.

Implementation of talis and dc house system for rural areas in indonesia

In 2017, the aggregate electrification ratio in Indonesia has been achieving 92.8%. However, some rural areas such as in Maluku and Papua Islands still have low electrification ratio (~70%). One of the main problems in supplying electricity to rural areas in Indonesia is the geographical concern which consisted of islands leading to the difficulty of electricity grid development. In some areas, diesel power plant has been being built to supply the electricity. However, it causes another problem to transport the primary energy source to the targeted area which would increase the cost of electricity supply. Besides, it also needs investment cost to build transmission and distribution systems, as well as the maintenance expenses. To resolve this issue, a new scheme of battery-based Tabung Listrik or TaLis (DC-based power bank) and DC house system is proposed to be the solution to provide electricity to rural areas. The potential of local renewable energy sources such as biomass, hydro, wind, and solar could be utilized to be charging sources of batteries (TaLis). This study presents the TaLis prototype, DC house installation, supply chain process and charging scheme of TaLis, and cost comparison between the proposed system with other existing power systems such as communal PV farm and diesel power plant. We found that TaLis and DC house system provided the least cost of electricity production compared to other power systems, i.e. $0.88/kWh for TaLis and DC house system, $1.65/kWh for diesel power plant, and $1.47/kWh for communal PV farm. Implementation of this approach is expected to improve the welfare and quality of life of rural communities immediately.

Study on Capacity and Operation Method of PEFC .MU.CGS for Apartment Using Measured Electricity and Hot Water Loads

The introduction of PEFC (polymer electrolyte fuel cell) μCGS (micro cogeneration system) into apartment is expected from the viewpoint of the energy saving effect in the home section. To introduce this system, the optimization of the equipment capacity of the fuel cell and the examination of its control method are indispensable. In this paper, therefore, the authors suppose a PEFC μCGS and examine its operation method based on the measured results of the electricity and hot water loads of an apartment in Fukuoka. At first, using the measured load patterns, the authors numerically determine the optimum operation schedule that maximizes the energy saving rate for various values of PEFC capacity and reveal the PEFC capacity suitable for the μCGS in both cases of each house installation and central installation. The relation between the seasonal change and the operation pattern of the PEFC in the case of central installation is also investigated. Next, the authors assume the central installation of the PEFC with the above suitable capacity, and propose a practically applicable prediction control method. The energy saving rate of the proposed control method is only a little lower than that of the optimum operation, indicating that the proposed control method has sufficiently high performance.
