当前含高渗透率可再生能源的微电网稳定运行问题日趋严重.通过场景生成与削减方法对可再生能源的随机性进行建模和求解;基于下垂控制理论,利用时间乘以误差绝对值积分指标实现微电网稳定性的快速判断;提出一种考虑可再生能源随机性的微电网经济性与稳定性协调优化策略.MATLAB/Simulink仿真结果验证了所提模型与方法的正确性与有效性.%Because of the high penetration rate of renewable energy,the stable operation of microgrid is seriously affected.The method of scenarios generation and reduction is applied to build and solve the model of renewable energy randomness.Based on the droop control theory,ITAE index is used to realize the fast judgment of microgrid stability.A strategy considering the randomness of renewable energy sources is proposed to coordinate the economy optimization and stability optimization of microgrid.Results of MATLAB/ Simulink simulation verify the correctness and effectiveness of the proposed model and method.
