The Control Mode of Distribution Grid/Off-Grid of Wind-Solar-Storage with Double Boost-Buck Converter Single Inverter Based on V2 Control Method
摘要
Abstract
Wind and solar hybrid power generation is widely used in agricultural and pastoral areas. In current applications, each system uses independent inverters, which requires higher cost and energy consumption. In this paper, a common DC bus scheme with dual Boost-Buck based single inverter structure was proposed, to realize wind and solar hybrid power generation. The proposed scheme can reduce cost and energy consumption. Firstly, topological structure and circuit of wind-solar-storage cogeneration system were designed based on V2 controlled double Boost-Buck converter. Hence the constant voltage value control can be achieved when the input voltage varies in a wide range. At the same time, voltage slope compensation method was used to suppress the self-excited oscillation of Boost-Buck circuit. Secondly, a series of control strategies were designed to improve storage stability, including stabilizing fluctuation of wind-solar, nine zoning following load, fuzzy charging and discharging. The seamless abutment between wind-solar-storage power and inverter was achieved. Thirdly, the benefit evaluation on the power consumption reduction of abandoned wind-solar was carried out. Finally, the software and hardware device were developed, according to the control modes of distribution grid and isolated island off-grid. The test and simulation were carried out. The output current of inverter shows good static and dynamic performance, stability and reliability, as well as better cost economy.关键词
