Research And Application Of Micro-grid Technology Based On Wind-PV-ES Hybrid System

Intensified energy crisis and environmental pollution,and now has become the world's major problems and challenges that we must face,how to rational development and utilization of clean renewable energy that we have to get started to become an important issue.Micro-grid energy storage device by using a system of various equipment,distributed power and micro-grid energy management systems and other components,such load power supply organization is a new application of technology.Application of micro-network technology can significantly improve the efficiency of renewable energy worldwide.Similarly,efficient solution to the negative effects of distributed generation and network generated.Currently study of micro-grid,most studies scenery storage systems are complementary to the micro-grid system.This is because each part of the scenery storage complexes,can make full use of solar energy and wind energy output compensation,good stability of the system,the energy storage device may be configured to reduce capacity.This paper summarizes the situation of foreign and domestic micro-grid construction,and the detailed analysis of the research progress of micro-grid related technologies,introduces the composition of the micro-grid,micro-grid constituting the various types of power are also analyzed.In the micro network control and management,through detailed analysis of the micro-grid energy management system,initially identified a micro-control network.On this basis,for the detailed design of Sino-Singapore Tianjin Eco-city(SSTEC),micro storage network building program to achieve the micro-grid system.Finally,Sino-Singapore Tianjin Eco-city(SSTEC)micro-grid system to run the test system and benefit analysis,curve and test data showed that the micro-grid system is running in good condition,having considerable economic,environmental and social value.
