Optimal Energy Allocation of Microgrid Based on Reliability and Economy by Considering Characteristics of Micro Source

针对孤岛运行模式,提出了一种兼顾可靠性和经济性的能量优化配置模型。该模型可根据实际情况灵活调整可靠性与经济性的相对重要程度比重;基于蒙特卡洛仿真建立微电源输出功率序列,基于自适应型离散粒子群算法在不同运行策略、储能最大容量以及柴油机额定容量下进行优化仿真,分析各因素对可靠性、经济性及环境的综合影响。算例仿真结果验证了所建模型的有效性。

An optimal energy allocation model is presented under stand-alone mode which takes reliability and economy into account; this proposed model can adjust the proportion of relative importance of reliability and economy flexibly according to the actual situation. Power source output sequence is established based on Monte Carlo simulation. The impact on reliability, economy and environment of the different operation strategy, the maximum capacity of energy storage and the rated capacity of diesel engine are analyzed based on the simulation of optimal energy allocation using adaptive particle swarm optimization method. The example result shows the effectiveness of the model.
