Operation And Optimization Of Hybrid Microgrid For Wind Power, PV And Energy

As the environment and energy issues become more prominent, the Microgrid has been paid much attention by governments. The promotion and popularization of micro grid can significantly reduce the emission of greenhouse gases and promote the adjustment of energy structure. Micro Grid distributes power, energy storage device, control system and power load integration, which is the main mode of operation in the future. The load forecasting technology and load distribution of Micro Grid are one kind of important optimization problems in power system. Because of the different power characteristics and operation modes of Microgrid and traditional power grid, the load distribution methods are different. To solve this problem, the following research is carried out in this paper:Firstly, the main characteristics of Microgrid are analyzed, and the research hotspot and research trend are summarized. The differences between the micro grid and the traditional method are analyzed;Then, according to the wind power generation and photovoltaic array in the micro grid, the output characteristics of the wind power generation units and the power forecasting methods are proposed, and the simulation results are com pared;Next, the model of the micro power cost functions are modeled, based on the robust scheduling method, which solves the uncertainty of the wind power and PV forecasting. Based on the simulation results, it is found that the load distribution method is superior to the offline load distribution method, which has certain theoretical value and practical significance.Finally, on the basis of the above research results, this paper summarizes the innovation points and the main work, and the future work is prospected.
