Research On Energy Complementation Of Biomass Power Generation Coordinating With Wind Power Generation

Wind energy is a kind of clean and renewable energy, its position in energy structure is more and more important. Researching on the development of wind power has an important role in China’s power industry. But, wind power’s volatility and uncertainty have seriously hindered the development of wind power. It can effectively solve the problem by way of biomass energy complementing wind energy. In this paper, we have made a systematical study on energy complementation of biomass power generation coordinating with wind power generation based on the characteristics of wind turbine generators output has been studied. The main contributions of the paper are as follows:The structure and characteristics of wind power system and biomass gasification generation system are studied. The wind is simulated by setting up a four-component model; wind speed is forecast through neural networks’ predicting; a wind turbine model has been built, the wind turbine generators’ predicted power output has been simulated. Gasification process, gas cleaning processes and gas-fired generation process in biomass gasification generation system are elaborated.Cooperative and hybrid power generation program is designed based on the analysis of the complementary characteristic of wind and biomass, as well as biomass generators operational planning in the complementary system is designed. The capacity ratio of wind power and biomass power is researched according to wind turbines output.Complementary program is to be optimized load sharing to achieve the optimal combination of the two power generation. The amount of raw materials of biomass generators consuming in unit time interval is considered as the objective function, the partial load efficiency of biomass generators, minimal start/stop time interval and system load balancing are used as constraints, the mathematical model of energy complementary system has been established. The unit commitment and optimal scheduling among the biomass generators in complementary system are researched by using BPSO.The results show that program of the hybrid power system made up wind power and biomass power is feasible. It can achieve complementary energy goals. BPSO achieves optimal scheduling of hybrid system so that all generators run at a reasonable state.
