随着市场机制引入电力工业,市场条件下的电力系统可靠性和系统运营经济性之间的矛盾逐渐显现出来,如何在电力市场的运营过程中保证系统运行的可靠性已成为研究的热点。文中总结了在研究电力系统可靠性和经济性关系方面已有的成果,展望了未来的研究方向。认为在电力市场的条件下,传统的可靠性指标体系已经无法适应新形势的需要,必须提出新型的将系统可靠性和运营经济性融为一体的可靠性指标体系;在电力市场环境中,系统和元件可靠性不应被视为系统运行的约束,而应将其看做一种稀缺资源,应当探索利用市场机制保证系统运行可靠性的途径。
With the introduction of the market mechanism into the power industry, the contradiction between the reliability of the power system under the market conditions and the economic efficiency of the system has gradually emerged. How to ensure the reliability of the system operation during the operation of the power market has become a hot issue. The paper summarizes the existing achievements in the study of the relationship between power system reliability and economy, and looks forward to the future research direction. In the electricity market environment, the traditional reliability index system can not meet the needs of the new situation. We must propose a new reliability index system that integrates the system reliability and the operation economy. In the electricity market environment, the system And component reliability should not be seen as a constraint on the operation of the system but rather as a scarce resource and ways of using market mechanisms to ensure system reliability should be explored.
