摘要
近年来,在居民侧实施热电联产和供热电气化受到了广泛关注。居民小区主要能源需求为电能和热能,主要能源输入为电能和天然气,可以采用能源中心概念来描述居民小区能源需求与能源输入间的耦合关系。在此背景下,首先构建了以热电联产和热泵作为能源转化装置的居民小区能源中心架构。然后,发展了居民小区能源中心内部优化运行的确定性模型,并将电动汽车集群负荷作为可控电负荷参与优化运行。考虑到居民小区的能源需求具有不确定性,且能源中心决策者制定调度策略时对风险的偏好也未必相同,为获得风险厌恶型决策者和风险偏好型决策者的调度策略,引入了信息间隙决策理论建立鲁棒优化模型和机会获利模型,进而建立了居民小区能源中心混合整数线性规划模型,并采用CPLEX求解。最后,以某居民小区为例来说明所发展的模型与方法的基本特征。
In recent years, the popularization of combined heat and power generation and electric heating has attracted extensive attention. The main energy demands in a residential quarter are heating demands and electricity demands, and the energy hub can be used to descript the coupling relationship between the energy demand and the energy input. Given this background, this paper firstly presents a mathematical model for the residential quarter energy hub, with the combined heat and power generation and the heat pump as energy devices. Then, this paper constructs the deterministic model of the residential quarter energy hub operation optimization, and considers the charging load of electrical vehicles as a controllable load to participate in the operation optimization. Energy demands of a residential quarter are uncertain, and various decision-makers may have different risk preferences in determining optimal operation strategies. With this consideration, this paper employs the information gap decision theory （IGDT） to develop the robust optimization model and the opportune-windfalling model respectively, in order to obtain the scheduling strategy of risk-aversion decision-makers and risk-preference decision-makers. And then, this paper constructs the mixed integer linear programming model and adopts the CPLEX to solve the model. Finally, a residential quarter is employed to demonstrate the essential characteristics of the developed model and method.
