Abstract

The increasing penetration of Plug-in Electric Vehicles (PEV) in the transportation system has increased the burden on the power system. This has made peak load demand management a challenging task for the power grid. To address this issue, a novel dynamic demand response pricing strategy in a grid-renewable generation integrated charging station environment is proposed in this paper. Renewable energy sources reduce the cost of generation and grid integration makes the system reliable. The proposed strategy models a Stackelberg game to provide dynamic prices for charging, discharging and grid power supplied for charging stations. Uncertainty and economics of renewable generation are considered for effective analysis and evaluation of the feasibility of the proposed strategy. The study considers the bidirectional flow of power and the battery degradation cost. Charging coordination is performed to optimize the cost of charging and discharging and support the grid in peak load demand management. Random charging behaviour and other parameters of PEVs are simulated using a random distribution function to resemble the real-time environment. A numerical case study validates that the proposed strategy has optimized the cost of charging and discharging and the serving capabilities of the charging station are enhanced with existing infrastructure.

可再生电网集成充电站中的动态定价策略与 PEV 充电协调

插电式电动汽车（PEV）在交通系统中的普及率越来越高，加重了电力系统的负担。这使得高峰负荷需求管理成为电网的一项挑战性任务。为解决这一问题，本文提出了一种在电网-可再生能源发电一体化充电站环境下的新型动态需求响应定价策略。可再生能源降低了发电成本，而电网一体化则提高了系统的可靠性。所提出的策略以斯泰克尔伯格博弈为模型，为充电站的充电、放电和电网供电提供动态价格。考虑了可再生能源发电的不确定性和经济性，以有效分析和评估拟议战略的可行性。研究考虑了电力的双向流动和电池退化成本。通过充电协调来优化充放电成本，并支持电网进行高峰负荷需求管理。使用随机分布函数模拟 PEV 的随机充电行为和其他参数，以模拟实时环境。数值案例研究验证了所提出的策略优化了充放电成本，并利用现有基础设施提高了充电站的服务能力。

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
