【摘要】：日益增长的电动车充电负荷给电力系统的运行调控提供了新的调度资源。针对电动车的充电调度问题国内外已开展大量研究。但尚未形成合理的市场机制,往往忽略车主的主动参与,同时缺乏工程应用。本文以电动车充电控制为切入点对电力系统需求侧响应实施的市场机制和工程实践进行探讨。在建立电动车充电负荷模型和研究电网负荷调控需求的基础上,分析了需求侧响应的市场机制,提出了通过用户报价反映车主个性化需求的电动车充电协同调度方法,开发了响应频率波动的电动车充电控制装置。首先,建立了电动车充电负荷模型,作为电动车充电负荷调控的基础。基于用户出行行为特性分析了用户接入电网时间和充电需求。通过对充电设备和动力电池建模分析了电动车充电功率控制方式。通过构建充电控制情景和用户决策模型对电动车充电控制方式进行分析。基于所建立的电动车充电负荷模型提出了一种电动车充电调控容量边界分析方法,并进行算例分析。其次,分析了电网分时分区的负荷调控需求,作为电动车充电负荷调控的目的。从功率平衡控制角度分析了负荷调控参与电网调峰和调频控制需求。从电力传输角度分析了负荷调控参与电网阻塞控制需求。从系统运行的角度分析了负荷调控参与系统备用需求。进而明确了电动车充电控制进行需求侧响应的方式和场景。最后,对电动车充电控制参与电力市场的模型和方法进行了探讨,作为电动车充电负荷调控的方法。根据电网负荷调控特性建立了分时分区的电动车充电控制构架。在构建电力市场模型的基础上分析了电动车充电进行需求侧响应的交易流程。基于电力系统分布式方向发展的趋势提出了电力系统协同调度方法。分别基于实时电价理论的节点电价和当前售电市场的偏差电量考核对需求侧响应定价机制进行了分析。开发了一套响应电网频率波动的电动车充电控制装置,并根据电网事故备用需求建立了相应控制策略。基于城市电网算例对电动车不控充电和智能充电两种场景下的电动车充电控制效果进行了分析。本文的创新点包括:1)基于当前售电市场环境分析了基于偏差电量考核的需求侧响应定价方法;2)提出了一种通过用户设置报价反映车主个性化需求的电动车充电协同调度方法;3)开发了一套响应电网频率波动的电动车充电控制装置。本文通过分析需求侧响应定价机制为电力系统实施需求侧响应定价提供了依据。通过设计计及用户报价的电动车充电协同调度方法考虑了车主参与电网调控的个性化需求。通过开发响应电网频率波动的电动车充电控制装置为电动车充电控制工程实践提供了借鉴。
[Abstract]:The increasing charge load of electric vehicles provides a new dispatching resource for the operation of electric power system. A large number of researches have been carried out at home and abroad on the charge scheduling of electric vehicles. However, the reasonable market mechanism has not been formed, the active participation of vehicle owners is often ignored, and the engineering application is lacking. In this paper, the market mechanism and engineering practice of power system demand-side response are discussed from the point of view of electric vehicle charging control. Based on the establishment of electric vehicle charging load model and the study of power grid load control demand, the market mechanism of demand-side response is analyzed, and a charging cooperative dispatching method is proposed to reflect the individualized demand of vehicle owners through user quotes. A charge control device for electric vehicle responding to frequency fluctuation is developed. Firstly, the charging load model of electric vehicle is established, which is the basis of charge load regulation of electric vehicle. Based on the characteristics of user travel behavior, user access time and charging requirements are analyzed. Through the modeling of charging equipment and power battery, the charging power control mode of electric vehicle is analyzed. The charging control mode of electric vehicle is analyzed by constructing charging control scenario and user decision model. Based on the electric vehicle charging load model, a boundary analysis method for charge control capacity of electric vehicle is proposed, and an example is given. Secondly, the demand of load regulation in time-sharing area is analyzed as the purpose of charge load regulation for electric vehicles. From the point of view of power balance control, the demand of load regulation for peak-shaving and FM control is analyzed. From the point of view of power transmission, the demand of load regulation and control for power network congestion control is analyzed. From the point of view of system operation, load regulation and control are analyzed to participate in system reserve requirements. Furthermore, the way and scene of the demand-side response of electric vehicle charging control are clarified. Finally, the model and method of electric vehicle charge control participating in electric power market are discussed, which can be used as the method of electric vehicle charge load control. According to the load control characteristics of electric network, a time-sharing area electric vehicle charging control framework is established. Based on the model of electric power market, the transaction flow of demand-side response of electric vehicle charging is analyzed. Based on the trend of distributed power system development, a power system cooperative dispatching method is proposed. The demand response pricing mechanism is analyzed based on the real time electricity price theory and the bias electricity quantity assessment in the current electricity market. A set of electric vehicle charging control device responding to the frequency fluctuation of electric vehicle is developed, and the corresponding control strategy is established according to the standby requirement of power network accident. Based on the example of urban power grid, the effect of electric vehicle charging control under two scenarios of uncontrolled charging and intelligent charging is analyzed. The innovations of this paper include: 1) based on the analysis of the current electricity market environment, the demand-side response pricing method based on the bias electricity quantity assessment is analyzed. A charge control device for electric vehicle (EV) is developed, which is responsive to the frequency fluctuation of electric network. Based on the analysis of demand-side response pricing mechanism, this paper provides a basis for power system to implement demand-side response pricing. In this paper, the individualized demand of vehicle owners to participate in power grid regulation is considered by designing a charging cooperative dispatching method that takes account of user quotes. The development of electric vehicle charging control device responding to the frequency fluctuation of electric network provides a reference for electric vehicle charging control engineering practice.
