针对电动汽车负荷接入智能小区,可能进一步加剧用电无序性,造成高峰负荷和高电费问题,需要对小区进行智能用电控制。在对小区负荷进行分类基础上,提出可平移负荷用电需求模型和电动汽车充放电需求模型。基于分时电价提出改进电价模型,进一步建立智能用电控制模型。通过BPSO和QPSO算法求解智能用电控制模型,实现可平移负荷和电动汽车负荷协调有序用电。以100户的智能小区为例,分析比较优化前后负荷曲线和用户电费,结果验证了智能小区用电控制的有效性和可行性。
Access to intelligent residential areas for electric vehicles may further aggravate the disorder of electricity supply, resulting in peak load and high electricity tariffs, and require smart electricity control for the residential area. Based on the classification of residential load, this paper proposes a demand model of translatable load and a demand model of electric vehicle charging and discharging. Based on the time-share electricity price, an improved electricity price model is proposed to further establish a smart electricity control model. The smart electricity control model is solved by BPSO and QPSO algorithm to realize coordinated and orderly power consumption of translatable load and electric vehicle load. Taking the intelligent community of 100 households as an example, the load curves before and after the optimization and the electricity tariff of the users were analyzed and compared. The results verified the validity and feasibility of the electricity consumption control in the intelligent community.
