摘要
以含风光储的交直流混合微电网为研究对象,通过聚类分析方法对气象条件进行分类,搭建风光储出力概率模型并进行序列化。提出一种序列运算方法计算交直流混合微电网用电不足期望值,从而迭代求得可信容量,针对风光装机容量配比以及直流负荷敏感度对可信容量的影响进行了分析,并将计算结果与蒙特卡洛法进行了对比,验证该文所提方法的正确性与有效性。
Reliability and credible capacity are the important indices of AC/DC hybrid microgrid. Considering the meteorological conditions classified by cluster analysis,a probabilistic power output model of wind/photovoltaic/storage of the AC/DC hybrid microgrid is established in this paper. A sequential operation theory is proposed to calculate the expected energy not supplied(EENS)value of AC/DC hybrid microgrid. With the iterative method,the credible capacity is solved. And the influence of wind farm/photovoltaic capacity ratio and DC load sensitivity are analyzed. The results are compared with Monte Carlo methods so that the validity and feasibility of the proposed method are verified with the example system.
