    摘要:

    家庭微电网中包含光伏和电动汽车等不确定性电源和负载,没有合理的能源管理策略容易导致家庭微电网失稳。在V2G系统中构造了一个同时考虑电动汽车、住宅、电池和可再生能源发电系统的模型。在电动汽车充放电的约束条件下,制定了住宅与微型燃气轮机的发电计划,提出了一种动态能源管理方法。最后通过仿真对所提家庭微电网能源管理策略进行验证,通过对比电动汽车随机充电和有序充放电情况下微电网的等效负荷以及储能运行情况,验证了约束电池的充电状态前提下的能源管理方案的合理性。

    Abstract:

    The home microgrid contains uncertain power sources and loads such as photovoltaics and electric vehicles. The lack of a reasonable energy management strategy can easily lead to instability of the household microgrid.In the V2G system, a model that simultaneously considers electric vehicles, houses, batteries, and renewable energy power generation systems is constructed. Under the restriction of electric vehicle charging and discharging strategy, a power production planning for the residence and for the microturbine is determined.Then a dynamic energy management is proposed. Finally, the proposed home microgrid energy management method is verified by simulation. By comparing the equivalent load and energy storage operation of the microgrid under the conditions of random charging, orderly charging and discharging of electric vehicles,the feasibility of proposed method is verified when the charging state of the battery is restricted.
