Aiming at the problems that the scale of distribution network investment is gradually increasing and the investment effectiveness still needs to be improved, the paper propose a comprehensive assessment system of input-output benefit for distribution network construction project. Firstly, select input-output benefit indexes basing on key factors. Secondly, propose index evaluation criterion determining...
This paper stands on the perspective of smart grid and smart electricity needs, presenting the concept of distributed power, making depth study on two levels of “Plug and Play” device information exchange and “Plug and Play” management technology after that. Firstly, the paper presents status of research studies at home and abroad. On this basis, for different forms of distributed power access, the...
The present study, firstly, puts forth a comprehensive and reasonable reliability assessing theory system directing at fuzzy layers and the incomprehensive factors of current distribution network. Next, the four major characteristics influencing reliability of the distribution system have been defined and research has been conducted on grade one and grade two as well as basic index involving those...
This paper dissertates the advantage of wind-solar complementary power supply system from the complementarities of time and region. It describes the development of wind-solar complementary single-phase sine wave power inverter and presents its hardware structure, operation principle, and intelligent control method to design for charging and discharging. Some key techniques such as the circuit topology...
