[Abstract]:In the face of the global cost of fossil fuels, Limited reserves and more and more serious environmental crises, renewable energy has been widely concerned by the governments and people of all countries. Wind and solar energy, as the endless and inexhaustible wealth of the earth, have become the focus of the people of renewable energy and have been widely used. As one of the main ways of utilizing solar and wind energy, photovoltaic and wind power generation technology is mature. Due to the randomness, intermittency and instability of wind and solar energy, in order to improve the efficiency of energy conversion and energy utilization, wind power and photovoltaic power generation based on wind and photovoltaic power generation combined power generation technology came into being. The control strategy is an important factor affecting the overall power generation efficiency in the wind and wind power generation system. Based on the summary of wind power generation, photovoltaic cell power generation and energy storage system, this paper analyses the working principle and establishes the frame diagram of the wind and solar energy storage system, and gives the individual wind, photoelectric and energy storage. The power control scheme, the grid connected current control method and the control strategy of the energy storage system. (1). The wind and wind power generation system is introduced. The wind power generation system and the photovoltaic power generation system in the wind and solar power generation system are summarized respectively. The principle of wind power generation is introduced, and the details of the wind power generation system are introduced. This paper introduces the composition and classification of the wind power generation system, and selects the doubly fed wind power generation system as the wind power unit of the wind and solar power generation system. In view of the photovoltaic power generation system, the principle of photovoltaic power generation is introduced in detail. The classification of the photovoltaic cells and the grid connected power generation system are briefly introduced. (2) the peak Pinggu and the power control of the power generation system are briefly introduced. Four control modes of energy storage system are introduced: tracking plan power mode, smooth power output mode, system FM mode, load peaving Pinggu mode. The principle of regulation and regulation of various control modes and the principle of peak peak Pinggu in energy storage system are explained. The algorithm of battery model and battery charging and discharging control strategy is analyzed. Now, for the energy storage system, it mainly introduces its classification and selection standards, and chooses the storage battery as the energy storage unit of the wind and solar energy storage system. It introduces the effect of the energy storage system in the peak peak Pinggu in the wind and scenery combined power generation system, and studies the overall power control strategy of the system of wind and solar energy storage system. According to the given control strategy, the active power control and reactive power control of the joint power generation system are analyzed in detail. The power control strategy of the wind generator system, the photovoltaic electronic system, the energy storage subsystem and the corresponding control strategy chart are given in detail. Finally, the control strategy is analyzed in detail. Finally, the control strategy is analyzed in detail. Finally, the control strategy is analyzed in detail. The control strategy of charge and discharge of the battery is given. (3). The control of grid current control and inverter bandwidth control is studied in view of the grid connected current and the DC/AC inverter dead zone bandwidth in the wind and solar energy storage system. The DC component and the instability of the grid current in the wind and solar power generation system are studied, and the PR control is carried out. The system is replaced by a quasi PR controller (QPR) with harmonic compensation and more practical, and applied to the DC control of a three-phase grid connected inverter. In the improvement of the traditional PR controller, the amplitudes and phases are modified by the proportions and phase compensators respectively, and a new controller is designed and used in the steady-state error control of the grid connected current. In view of the current dead zone of the grid connected inverter, the traditional control strategy is corrected, and a new control strategy is obtained. The new control strategy is applied to the inverter dead band bandwidth control, and the simulation analysis of the three controllers is carried out in the double closed loop control system.
