基于微观经济学均衡原理的电力市场清算模型

A Clearing Model for the Electricity Market Based on the Equilibrium Principle of Microeconomics

以清洁能源为主导,以电为中心是未来能源发展的必然趋势。近年来,由于电力系统的放松管制,电力行业进入了一个竞争日益激烈的时代。然而,电力市场不应该是完全竞争的,需要严格监管以满足电力系统的安全可靠运行。基于微观经济学中的市场均衡原理,本文提出了一个新的有限竞争的电力市场清算模型,其中有限竞争的电力满足了电力流量调节和网络损耗分配。此外,通过所建市场清算模型,分析了可被视为衡量电力市场放松管制程度的自由交易比率。最后,用IEEE-30测试系统进行了三个案例研究,以验证该方法的实用性和效率。结果表明,不同的交易比率对电力系统的运行有显著影响,并且可以确定最佳的交易比率。

Taking clean energy as the mainstay and electricity as the center is an inevitable trend for future energy development. In recent years, due to the deregulation of the power system, the power industry has entered an increasingly competitive era. However, the electricity market should not be completely competitive and requires strict regulation to ensure the safe and reliable operation of the power system. Based on the principle of market equilibrium in microeconomics, this paper proposes a new limited competition electricity market clearing model, where the limited competition electricity meets the requirements of electricity flow regulation and network loss allocation. In addition, through the established market clearing model, the free trading ratio that can be considered as a measure of the degree of deregulation in the electricity market was analyzed. Finally, three case studies were conducted using the IEEE-30 testing system to verify the practicality and efficiency of this method. The results indicate that different transaction ratios have a significant impact on the operation of the power system, and the optimal transaction ratio can be determined.
