摘要
为有效处理基于光伏的分布式发电过程中存在的过电压和过载问题,在研究了低压配电系统功率流、光伏发电、需求响应等模型的基础上,提出了一种基于需求响应机制的柔性负荷模型。该模型为一个典型的非线性规划问题,可通过PSO算法进行求解。仿真阶段,利用基于光伏的分布式低压馈线模型验证所提柔性负荷模型,结果表明,所提模型能够将需求进行转移,且电压和电流均满足限制条件。实验结果也进一步验证了该模型能够提升能源利用效率。
In order to deal with the over-voltage and overload problems in the process of distributed generation based on photovoltaic,a flexible load model is proposed based on the study of power flow,photovoltaic generation and demand response models of low-voltage distribution system.The model is a typical nonlinear programming problem,which is solved by PSO algorithm.In the simulation phase,the proposed flexible load model is verified by the photovoltaic distributed low-voltage feeder model.The results show that the proposed model can transfer the demand,and the voltage and current meet the constraints.The experimental results also further verify that the proposed model can improve energy efficiency.
