With the rapid development of the global economy, the interconnection of power grids has become an objective law and a trend of the power industry development. The implementation of power grid interconnection projects, especially transnational power grid interconnection projects, will bring us substantial benefits. To demonstrate these benefits comprehensively, we designed a comprehensive evaluation index system with multiple international engineering characteristics. The index system takes the influencing factors of economic, social, environmental and technical benefits into account. In order to improve the rigidity and power of weight determination, we proposed the least squares method which combines the order relation method and the factor analysis method. Furthermore, the limitation of the one-way evaluation was effectively overcome by combining TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution), grey relation analysis method and vector projection method. In addition, we adjusted the potential impact of the time on evaluation by using the quadratic weighted algorithm, so that we can dynamically evaluate the comprehensive benefits. Finally, we verified the established index system and evaluation model through an example of eight different investment plans of a transnational high voltage direct current (HVDC) transmission project. Altogether, results from this paper will provide a guidance reference and decision support for the grid corporation to invest in transnational power grid interconnection projects.

With the rapid development of “Internet plus” in our country, the scope of its influence is also constantly expanding. Especially in recent years, China puts forward “mass entrepreneurship and innovation”, which makes the “cloud analysis” and “Internet plus” and “innovation” to start cross-border integration. Starting with the background, development stage, environment and other aspects of Internet-plus entrepreneurship and innovation under the cloud analysis, this paper analyzes the influence of various factors in the process of Internet plus entrepreneurship and innovation and the influence degree of various factors on entrepreneurship and innovation in depth, constructs the entrepreneurship and innovation evaluation index system based on the “Internet plus”, and finally, combined with an example to verify the index system and fusion analysis method. The verification results show that the “Internet plus” entrepreneurship and innovation based on the perspective of cloud analysis in this paper can not only directly demonstrate the promoting factors of “entrepreneurship and innovation “under Internet plus”, but also be scientific and effective when evaluating the “Internet plus” entrepreneurship and innovation activities from the perspective of cloud analysis.

In the background of energy transformation, the world has witnessed the rapid development of new energy generation, with the proportion of capacity and electricity continuously increasing. However, different countries and regions have great differences in the access level of new energy. When a high proportion of new energy is connected to the system, it is neither scientific nor reasonable to reflect the development and absorption level of new energy only by such indicators as the proportion of new energy installed and the proportion of electricity generated. This paper analyzes the development status of new energy at home and abroad, and constructs the evaluation index system of the access level of new energy in power grid. Based on the evaluation index system, the access levels of new energy in different countries and regions are compared and analysed. At last, several key issues that need to be solved to achieve the goal of high proportion of new energy access in China are put forward.

With the development of society, environmental issues have been given more and more attention, and the improvement of public awareness, legal and environmental standards promote the rapid development of green supply chain. Combining with catastrophe progression method (CPM), enterprises who implement green supply chain are provided scientific and effective ways to manage company. Firstly, the evaluation process of CPM is given. Secondly, a set of green supply chain performance evaluation index system is designed on the basis of the connotation of green supply chain and environmental management standards, and the index system is designed by using dimensionless process. Finally, numerical examples show that the performance evaluation of green supply chain based on CPM has a higher scientific and practical application value.

Based on the perspective of cost risk management of the entire process of power grid construction project, the WBS-RBS risk identification method is applied. The risk factors of power grid engineering cost are comprehensively identified from the five major engineering cost formation stages: investment decision estimate stage, design estimate stage, bidding price stage, construction budget stage, and final account stage. Combined with the basic data obtained from the questionnaire, the membership degree method is adopted to screen the key indicators of the preliminary factors of cost risk and then eliminate the redundant indicators. Furthermore, a set of simple and efficient risk evaluation index system for power grid engineering cost is constructed in order to improve the risk evaluation and management level of power grid construction project in China.

With integrated consideration of existing research on power grid development evaluation index system and requirements of power grid development diagnosis, a more comprehensive power grid development diagnostic index system is established from five aspects of power grid security and reliability, high efficiency, coordination, economics and social environment and more than 20 indicators. In addition, a new power grid development diagnostic evaluation method based on hierarchical analysis and multi-level fuzzy comprehensive evaluation is proposed in order to diagnose and assess power grid status quo and the actual level of development comprehensively, objectively and systematically ,which will help power grid enterprises conveniently to find the main reason of affecting the power grid and enterprise development and encourage enterprises to continuously improve the targeted improvement measures and the level of grid development.

The demand of electricity is growing fast in recent years, the electricity supply situation was tense especially in summer and winter, power emergency brownouts as effective measures to ease power tensions, has become an important part of demand-side management. Grid Emergency-order arrangement affects the scheduling and reliability of electricity, but also directly affects the user's production and life. This article establishes a grid emergency order bit of evaluation index system from the angle of environment, resources, economy and user perspective, and uses the normalization and AHP analysis to empower indexes.

Most power grid companies are asset-intensive and technology-intensive companies. Therefore, the quality and health of assets and equipment are crucial to the sustainability of the development of power grid companies and the safety of power grid development. To power grid companies through multiple dimensions Decompose the evaluation index of asset health, find the key factors affecting the asset health evaluation of power grid enterprises, and find a way to solve the problem for the subsequent improvement of the health of power grid enterprises’ assets. This paper describes the SMART criteria for asset health assessment, combining the principles of index selection and index grading, and clarifies the principles of constructing the evaluation index system. On this basis, from the three dimensions of physical, economic and social, and considering the internal and external power grid enterprises, a multi-dimensional asset health evaluation index system has been established.
