摘要:

电力系统中新能源的高比例渗透使得频率稳定受到严重挑战。随着V2G的发展,电动汽车能够作为灵活储能资源为电力系统提供稳定的调频服务。为了使电动汽车能够为电网提供更大的调频容量,提高用户参与电网调频意愿,分析了电动汽车的行为特性、荷电状态及功率约束,对电动汽车出行链及其行驶区域交通网进行建模,提出优化电动汽车期望荷电状态约束方法,构建电动汽车弹性调频容量空间、激励机制和调频控制策略。仿真验证表明:与不考虑弹性充电需求的传统控制策略相比,考虑弹性充电需求的控制策略在为电网提供调频容量、增加用户调频收益等方面具有优势。所提出的控制策略能够为电网提供更大的调频容量,增加用户的调频收益,维持电网频率的稳定。

Abstract:

The high proportion of new energy penetration in the power system poses a serious challenge to frequency stability. With the development of vehicle to grid, electric vehicles as a flexible energy storage system can provide stable frequency regulation services for the power system. In order to enable electric vehicles to provide greater frequency regulation capacity for the power grid and increase users' willingness to participate in frequency regulation, the behavioral characteristics, state of charge, and power constraints of electric vehicles were analyzed. The travel chain and transportation network of electric vehicles were modeled, and a method for optimizing the expected SOC state constraint of electric vehicles was proposed, and the elastic frequency regulation capacity space, incentive mechanism, and frequency regulation control strategy of electric vehicles were constructed. Simulation has verified that compared with traditional control strategies that do not consider elastic charging demand, the proposed control strategy that considers elastic charging demand has advantages in providing frequency regulation capacity for the power grid and increasing user frequency regulation revenue. The proposed control strategy can provide a larger frequency regulation capacity for the power grid, increase users' frequency regulation revenue, and maintain the stability of the power grid frequency.
