The Micro Grid Control Strategy Research And Application

In today's world within the scope of the third generation of power grid development and construction of the beginning,the energy conservation and environmental protection,renewable energy and intelligent micro grid characterized gradually becomes a trend,with the development of technology,green environmental protection policy and is a combination of factors such as the reform of electric power market mechanism makes distributed generation for the future development of important energy option.The energy of the present stage our country still is given priority to with centralized power supply system,the development of distributed energy does not replace the traditional energy supply,will be a beneficial complementarity of the power system.About micro power grid construction need accurate suitable evaluation index system of micro grid is the basis of measuring micro power grid comprehensive benefit,help the operation of the power system operation personnel to understand the micro grid and determine the optimal way of trends,to develop a reasonable operation scheme,improve micro power grid investment,improve the utilization rate of equipment,to achieve the optimal allocation of resources.In view of the micro power grid to carry out the related research is mostly confined to the qualitative analysis,the simulation analysis and experimental observation,it is lack of systematic,excessive dependence on the basic theory and method of analysis,lack of detailed study of the specific scheme.Therefore,the research in the micro grid system structure,micro power grid of the configuration of distributed power supply and micro grid control strategy,the influence of the micro power grid for distribution network analysis and improvement measures such as subject,has become the urgent request of micro power grid planning and construction.Development and trend,this thesis is aimed at today's electricity island landscape hybrid energy storage system through simulation analysis,analysis of photovoltaic power station and wind farms need to take control strategy,and photovoltaic power station,the mutual influence between wind farm and power grid,and proposes the corresponding solution measures;Of east fushan island is renewable energy sources such as wind power and solar energy resources utilization and research,put forward the micro network timing and non timing start-stop control strategy;Yongxing island light/wind resources characteristic analysis,research design Xisha yongxing island-wind-light diesel complementary overall technical scheme of the power grid is isolated;Yongxing island-wind-light diesel complementary isolated grid energy management and operation mode of study and so on.
