摘要
随着能源市场化改革逐步推进,综合能源系统中各类能源在物理层面的耦合将逐渐扩展至市场层面。综合能源系统中各自独立运行的能源市场难以协调耦合的多能生产、使用,使得市场参与主体交易意愿难以充分满足,增大了物理系统运行风险。因此,提出了一种电-热综合能源市场出清机制,统一电、热的市场交易,并建立了电-热联合市场竞价双层模型,研究了计及供应侧策略投标的市场均衡。其中上层是电-热供应商,其目标是使自身收益最大化;下层是市场运营商的出清模型,其目标是电、热供需总体社会福利最大化。通过将下层市场出清问题转化为等效KKT条件,供应商的竞争均衡问题转化为带有均衡约束的均衡问题,并采用对角算法求解市场均衡。最后通过算例验证了该方法的有效性。
With the reform of energy market, multi-energy coupling in the integrated energy system(IES) will gradually expand from the physical level to the market level. The independent operation of the energy market makes it difficult to coordinate the coupling multi-energy production and utilization, so the independent market clearing may not meet the participants’ trading willingness, which increases the physical system operation risk. In this paper, a clearing mechanism is proposed for the electricity-heat integrated energy market to unified electricity and heat market transactions. A bi-level electricity-heat integrated market bidding model is established to analyze the supply side equilibrium. The upper level is the strategic offering of electricity-heat suppliers, whose goal is to maximize its own revenues. The lower level is the clearing model of the market operator(MO), whose goal is to maximize the social welfare of electricity and heat transaction. After translating the problem of the market clearing into the equivalent KKT condition, the supplier’s competitive equilibrium problem is transformed into an equilibrium problem with equilibrium constraint(EPEC). The diagonalization algorithm is used to solve the market equilibrium. Finally, the effectiveness of the method is verified by an example.
