Using the improved prospect theory with the linear transformations of rewarding good and punishing bad(RGPBIT),a new investment ranking model for power grid construction projects(PGCPs)is proposed.Given the uncertainty of each index value under the market environment,fuzzy numbers are used to describe qualitative indicators and interval numbers are used to describe quantitative ones.Taking into account decision-maker’s subjective risk attitudes,a multi-criteria decision-making(MCDM)method based on improved prospect theory is proposed.First,the[−1,1]RGPBIT operator is proposed to normalize the original data,to obtain the best andworst schemes of PGCPs.Furthermore,the correlation coefficients between interval/fuzzy numbers and the best/worst schemes are defined and introduced to the prospect theory to improve its value function and loss function,and the positive and negative prospect value matrices of the project are obtained.Then,the optimization model with the maximum comprehensive prospect value is constructed,the optimal attribute weight is determined,and the PGCPs are ranked accordingly.Taking four PGCPs of the IEEERTS-79 node system as examples,an illustration of the feasibility and effectiveness of the proposed method is provided. 展开更多

With the development of Internet of Things and smart grid, especially at the level of smart substations, there are more and more operational data. In order to monitor the operation status of power equipment in real time, it is necessary to study the online monitoring method of power equipment. At present, many scholars carry out on-line monitoring on power equipment to realize signal monitoring. The fault information model of intelligent substation and on-line monitoring method of relay protection are studied. The method mainly describes the coupling and correlation between relay protection state information, automatically identifies the key state of relay protection, and realizes relay protection fault location. Although power equipment can be monitored, there is a problem of poor real-time performance. Therefore, an on-line monitoring method for power equipment based on the Internet of Things technology is designed. Internet of Things technology originated from the media field and is the third revolution of information technology industry. The so-called Internet of Things refers to any object connected to the network through an information sensing device in accordance with the agreement. Objects exchange and communicate with each other through an information medium to realize intelligent identification, positioning, tracking, monitoring and other functions. Based on the advantages of Internet of Things technology, it is applied to the online monitoring of power equipment to improve the level of online monitoring of power equipment. Based on this, this paper studies the full-scale monitoring of power grid construction in the Internet of Things for reference. 展开更多

China needs to develop a strong national power grid which takes ultra-high-voltage (UHV) transmission systems as its core. The grid is expected to adopt 1000-kV-class AC and ± 800-kV DC transmission systems. In view of significant achievements in technological research and considerable progress in UHV manufacturing technology, China is capable of developing UHV systems. In order to promote the construction of UHV systems,China Electric Power Research Institute and other institutions have initiated first-phase research activities of UHV transmission technologies. The main contents involve research on UHV transmission technology and its economy,developing and manufacturing abilities on UHV equipment, prospective of UHV network frame and selection of demonstration projects, etc. 展开更多

The application of power communication technology in smart grid can improve the stability of smart grid operation and promote its all-round development. With Chinas economic development and social progress, the importance of technology has been very clear. Only by comprehensively improving the overall efficiency of the power grid operation can the economic development be promoted. At present, Chinas social demand for electricity is increasing, and power enterprises should innovate and develop, comprehensively lead the technical conditions to carry out intelligent construction of power grid, intelligent construction of power grid has become an important work. Technology is the key factor in the construction of smart grid. We should fully grasp the core of advanced technology, grasp the needs of market users, comprehensively strengthen scientific management, and continue to promote the process of smart grid construction. 展开更多
