Abstract
In view of the situation that the sustaining and stable operation of the micro grid only by batteries for ener-gy leveling and adjustment can not be met due to the intermittency and instability of PV output,the optimization method of energy storage capacity allocation in photovoltaic DC micro grid considering Hydrogen energy application is proposed.Considering the application of Hydrogen energy in photovoltaic DC micro grid,the photovoltaic cell,bat-tery,electrolyzer-Hydrogen storage tank-fuel cell are modeled and analyzed.The power leveling control strategy and hybrid energy storage charge and discharge management strategy are designed in accordance with the the model-ing analysis results.The maximizing annual net profit and PV self-absorption rate are taken as the optimization objec-tives,an optimization model of energy storage capacity configuration is set up to obtain the optimal configuration re-sult of energy storage capacity.The experimental results show that with application of the proposed method,the pow-er deviation rate of photovoltaic DC micro grid is significantly reduced,the peak load balancing capacity is effective-ly optimized,and the self-balance rate of the micro grid is greatly improved,indicating that the method has a good capacity allocation effect.关键词
