Sustainability Evaluation of Power Grid Construction Projects Using Improved TOPSIS and Least Square Support Vector Machine with Modified Fly Optimization Algorithm

The electric power industry is of great significance in promoting social and economic development and improving people’s living standards. Power grid construction is a necessary part of infrastructure construction, whose sustainability plays an important role in economic development, environmental protection and social progress. In order to effectively evaluate the sustainability of power grid construction projects, in this paper, we first identified 17 criteria from four dimensions including economy, technology, society and environment to establish the evaluation criteria system. After that, the grey incidence analysis was used to modify the traditional Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS), which made it possible to evaluate the sustainability of electric power construction projects based on visual angle of similarity and nearness. Then, in order to simplify the procedure of experts scoring and computation, on the basis of evaluation results of the improved TOPSIS, the model using Modified Fly Optimization Algorithm (MFOA) to optimize the Least Square Support Vector Machine (LSSVM) was established. Finally, a numerical example was given to demonstrate the effectiveness of the proposed model.

Risk Evaluation of a UHV Power Transmission Construction Project Based on a Cloud Model and FCE Method for Sustainability

In order to achieve the sustainable development of energy, Ultra High Voltage (UHV) power transmission construction projects are being established in China currently. Their high-tech nature, the massive amount of money involved, and the need for multi-agent collaboration as well as complex construction environments bring many challenges and risks. Risk management, therefore, is critical to reduce the risks and realize sustainable development of projects. Unfortunately, many traditional risk assessment methods may not perform well due to the great uncertainty and randomness inherent in UHV power construction projects. This paper, therefore, proposes a risk evaluation index system and a hybrid risk evaluation model to evaluate the risk of UHV projects and find out the key risk factors. This model based on a cloud model and fuzzy comprehensive evaluation (FCE) method combines the superiority of the cloud model for reflecting randomness and discreteness with the advantages of the fuzzy comprehensive evaluation method in handling uncertain and vague issues. For the sake of proving our framework, an empirical study of “Zhejiang-Fuzhou” UHV power transmission construction project is presented. As key contributions, we find the risk of this project lies at a “middle” to “high” level and closer to a “middle” level; the “management risk” and “social risk” are identified as the most important risk factors requiring more attention; and some risk control recommendations are proposed. This article demonstrates the value of our approach in risk identification, which seeks to improve the risk control level and the sustainable development of UHV power transmission construction projects.

Risk, Regulation, and Rhetorical Boundaries: Claims and Challenges Surrounding a Purported Nuclear Renaissance

This study examines the efforts of individuals and advocacy groups seeking to influence a state utilities commission's decisions regarding a large corporate merger and a nuclear power construction project. Such local engagements have wider significance as the nuclear industry attempts to expand its role in the global energy economy. Utilizing participatory field work and analysis of public documents, we extend the concept of rhetorical boundary work by examining two challenges faced by opponents of the merger and the nuclear project. First, the utilities commission's regulatory mandate is limited to economic risks rather than environmental, health, and safety risks. Second, expert authority is consistently privileged over local, vernacular arguments. We explore the rhetorical negotiation of these boundaries and the effects produced.

The Schedule Control of Nuclear Power Construction Phase of Project Approval and Administrative Licensing

As a clean and economic power, nuclear power has become an important part in China’s power structure. Nuclear power plant project has the characteristics of large investment and long period, thus requiring a strict schedule control. This paper deeply studied the work contents of China’s nuclear power project approval and administrative license, selectively analyzed the required supporting documents for this phase, and simplified the work into several phases. According to the feature of each phase, we created the “laddering” model; controlled the schedule in three respects, including: nuclear power connected to grid related supportive documents, nuclear power construction related supportive documents, and the nuclear power security and environmental protection related supportive documents. By realizing the schedule control of the phase in nuclear power project in this paper, we hope to further enhance the level of China’s nuclear power construction project managements, ensure the economic and security of nuclear power projects and better promoted nuclear power projects.

Exploring expert confidence in cost estimates for nuclear power engineering, procurement and construction projects - a survey of nuclear industry experts

Nuclear power is currently undergoing a renaissance because of increasing energy demand and the ability of nuclear power to provide low-emissions, base-load power supply. However, the industry has been historically plagued with considerable technology deployment risks, with project cost and schedule overruns presenting a significant risk to nuclear plant investors. Considerable uncertainties exist with new nuclear power deployment, and there is a lack of a standardised industry approach to characterising, assessing and acting on these uncertainties to limit the variability on eventual project performance. This study identifies the major causes of risks in nuclear power plant deployment projects, and the role of project risk-management, as defined as the framework for creating awareness, assessment and action on risk. The study is performed through both a literature review of nuclear power plant project risk documentation, interviews with subject matter experts and a survey of a cross section of nuclear industry experts.

How to implement a wind power project in China?—Management procedure and model study

To increase the supply of electricity and reduce environmental pollution, China has made an effort to boost the renewable energy. As a renewable energy, wind energy has been maintaining a rapid growth over the last ten years. China has the largest construction market for wind power in the world, so it attracts many local and foreign investors. However, because of the lack of a full understanding of China's complicated administrative procedure for wind power projects, many foreign investors have encountered difficulties when trying to enter the Chinese wind power market. According to the relevant laws, regulations, policies and project practices, this paper puts forward a main management procedure model for Chinese wind power projects as well as four subdivided process models, including the Project Approval Process, the Land Application Process, the Design Process and the Licensing and Construction Process. And then the administrative requirements, milestones and main points of works are identified and analyzed within the framework of the four processes. The results open a window through which both the local and foreign investors can perceive a panoramic procedure for wind power project construction in China.

풍력 발전소 프로젝트의 핵심성공요인

인류는 화석연료의 과도한 소비로 인해 심각한 환경문제에 직면하고 있으며 화석연료가 고갈됨에 따라 그 가격이 급등하고 있어 대체에너지에 대한 수요가 지속적으로 증가하고 있다. 이에 대한민국을 포함한 각국 정부는 대체에너지의 발전부담률 확대를 위하여 세제 혜택을 비롯한 각종 재정 지원을 제공함으로써 시장규모 확대를 모색하고 있다. 하지만 대체에너지는 그 역사가 짧고 국내의 경우 기술 수준도 상대적으로 뒤쳐져 있어 사업추진 시 다양한 시행착오를 경험하고 있는 실정이다. 이에 본 연구는 대표적인 대체에너지인 풍력을 대상으로 효율적이고 성공적인 사업추진을 위하여 핵심성공요인(Critical Success Factor, CSF)을 도출하였다. 문헌고찰을 통해 일차적으로 CSF를 도출한 뒤 표적집단면접법을 활용해 이전 단계에서 도출된 CSF의 적정성을 검토하고 몇 가지 요인을 추가해 총 25개의 CSF를 확정하였다. 이 결과에 중요도-성과도 분석(Importance-Performance Analysis, IPA)을 적용하기 위하여 관련 업계 종사자들에게 총 218부의 설문을 수집하였다. IPA를 통해 "프로젝트 금융", "타당성 분석", "정부 전력 매입단가", "발전기 선정" 요인이 우선적으로 관리해야 할 CSF라는 결론을 도출하였다. 마지막으로 네 가지 CSF를 효율적으로 관리하기 위한 방안을 제시하였다. 본 연구를 통해 도출된 CSF는 향후 풍력 발전 건설사업에 앞서 전 생애주기 관점에서 사업평가를 위한 도구로 사용될 수 있을 것이다. Climate changes caused by fossil fuel energy usages have led to serious environmental damages and resource scarcity. Ever-increasing demand for energy causes harsh competition in international energy markets. Nuclear power, which once was regarded as a desirable clean energy, began to face public oppositions after the Japanese nuclear disaster in 2011. In this context, wind power is now considered to be an ever-more important recyclable energy source. Thus, this study intended to identify critical success factors for wind power construction projects. After a thorough literature review, two focus group interview sessions were conducted. A questionnaire-based survey, coupled with the two previous methods, resulted in the extraction of important factors for the success of wind power projects. Experts, including those working as constructors, designers, and owners, were paid a direct visit for the interview and survey. The critical success factors were categorized into feasibility study, right policies, equipment selection, and project financing issues. The proposed critical success factors are expected to be an effective guideline for future investors in wind powers.
