含分布式電源的微網(wǎng)儲能系統(tǒng)控制研究
[Abstract]:Under the background of the increasing energy demand, the increasingly prominent air quality problem and the environmental protection problem becoming the recessive barrier to international trade, how to develop renewable energy safely and efficiently? In particular, clean energy such as wind power and photovoltaic power has become an urgent issue. As a relatively independent small generation and distribution unit, microgrid can greatly alleviate the problem of grid-connected distributed generation (DG) technology, and make it possible for more renewable energy to connect to the grid. In order to make the microgrid run safely and stably, it is necessary to access the energy storage system (ESS),) in the microgrid to ensure the continuous power supply of the important load in the microgrid when the main network fails. In this paper, the related control technology of microgrid energy storage system is studied, and the models of wind turbine, photovoltaic array and hybrid energy storage system are built. At the same time, in order to realize the maximum power point tracking of renewable energy generation, the variable step-size mountain climbing search method and photovoltaic array admittance increment method are studied respectively. In this paper, the theoretical basis of energy forming control method is analyzed, and the idea of energy storage system control from the view of energy is put forward, and the controller design of energy storage system based on energy forming is studied. The port controlled Hamiltonian (PCH) model of energy storage system is established when the island is running. Based on the PCH model, the energy forming controller of the energy storage system is designed by means of damping injection and interconnect matrix design method. The control method based on energy forming and the traditional PI control method are compared and analyzed by MATLAB/simulink simulation software, and the validity and feasibility of the energy forming method in the operation of isolated island are proved. The simulation analysis of energy forming control method and PI control method under grid-connected condition shows that the control performance of PI is better than that of energy forming control under grid-connected condition. The power distribution of the energy storage system is further analyzed and studied. The energy allocation of the energy storage system is optimized by introducing a low pass filter into the energy storage system. The simulation results of the energy storage system controlled by PI after the introduction of the low pass filter are also given.
