摘要
随着风电、光伏等分布式新能源的快速发展,以及电动汽车的广泛应用,利用虚拟电厂将二者与更多的分布式能源、负荷聚集在一起,已成为一种发展趋势.介绍了含电动汽车的虚拟电厂的基本架构,并将此类虚拟电厂的优化调度分为了两部分.第一部分是采用合理有效的措施引导电动汽车有序充电,主要包括电价型需求引导和激励型需求引导.电价型需求引导旨在根据电动汽车的负荷特性与虚拟电厂或电网的运营需求制定不同的充放电电价,引导电动汽车在合适的时间充放电;激励型需求引导旨在在分时电价的基础上对电动汽车用户采取额外的激励方式,进一步引导其充放电行为.第二部分是在保证电动汽车可靠接入后,搭建虚拟电厂的优化调度模型,对虚拟电厂内部各组成部分进行优化调度.
Abstract
With the rapid development of distributed new energy sources such as wind power and photovoltaics,along with the widespread operation of electric vehicles,the trend of integrating these sources with more distributed energy and loads through virtual power plants is emerging.This paper introduces the basic structure of virtual power plants with electric vehicles.The optimization dispatching of such virtual power plants is mainly divided into two parts.The first part involves adopting reasonable and effective measures to guide the orderly charging of electric vehicles,which primarily includes price-based demand response and incentive-based demand response.Price-based demand response aims to guide the charging and discharging of electric vehicles at required times by setting different tariffs according to the load characteristics of electric vehicles and the operational needs of virtual power plants or power grids.Incentive-based demand response,based on time-of-use tariffs,takes additional in-centive measures to guide the charging and discharging of electric vehicles.The second part involves building an optimized dispatch model for the virtual power plant after ensuring the reliable connection of electric vehicles,and optimizing the dispatch of components within the virtual power plant.
