摘要:

用户侧能源转型以终端电能替代和分布式可再生能源开发利用为主要途径,能够促进能源系统向清洁、低碳方向发展。在促进用户侧能源转型的背景下,研究了含多个决策主体的区域能源定价与管理策略。首先基于Stackelberg博弈提出了多主体交互的区域能源定价与管理机制。然后,基于用户收益对有限理性用户的激励特性,构建了包含能源供应者(ES)与多个用户代理(UA)的双层优化决策模型。在所构建的模型中,上层ES确定从能源生产者处购能的策略、所拥有设备的运行状态和能源价格,决策目标是出售能源的利润最大与出售化石能源的惩罚成本最小;下层各个UA分别根据能源价格配置电能替代设备,并调整用能策略,决策目标是各自投资与用能成本最低。接着,应用KKT(Karush-Kuhn-Tucker)条件以及强对偶理论、增量法、互补松弛条件转化方法,将非凸非线性的双层优化问题转化为单层的混合整数线性规划问题。最后,以某含有居民取暖热负荷、工业热负荷、燃油汽车和光伏发电资源的区域为例,说明所提出策略的可行性与有效性。

Abstract:

The user-side energy transition,takes electric energy substitution in energy consumption sector and the development and employment of distributed renewable energy generation as the main ways,which can promote the energy system to develop in a cleaner and lower-carbon way. In the background of promoting user-side energy transition, the energy pricing and management strategies of regions containing multiple decision entries are addressed. Firstly, a mechanism for energy pricing and management is proposed based on the well-established Stackelberg game considering the interactions among multiple decision entries. Secondly, a bi-level optimization model with an energy supplier (ES) and multiple user agents (UAs) included is established based on the incentives of profits to bounded-rational UAs. In the presented model, the ES in the upper layer determines the energy procurement from the energy producer, and operating schemes of self-owned devices as well as regional energy prices, with the objectives of maximizing the profits of energy sales and minimizing penalty costs of selling fossil energy. Each UA in the lower layer invests devices and adjusts energy consumption strategies according to energy prices, with an objective of minimizing the costs of purchasing energy and investing devices. Thirdly,This non-convex and non-linear bi-level optimization model is transformed into a mixed integer liner programming problem, by applying the Karush-Kuhn-Tucker (KKT) optimality condition, the incremental method, the duality theory and relaxation technology. Finally, a sample example including residential heat load, industrial heat load, fossil-fueled vehicles and photovoltaic generation is employed to demonstrate the feasibility and effectiveness of the proposed method.
