【摘要】：近年来,电力市场化进程的进一步加快,电力系统运行过程中存在互相影响的两个因素——市场以及安全风险。为进一步保障电力系统安全稳定运行、电力市场良好发展,我们将立足电力系统安全度及充裕度,以电力交易过程中考虑可靠性为重点,研究其原理和方式,提供理论支持。本文引用了将电力系统可靠性作为一种资源引入电力市场的理念,研究了在充裕度市场中市场组织方式、市场成员申报方式、交易商品类型等,进一步构建了充裕度市场的交易算法。初步建立了电力市场单个成员对系统充裕度影响的方法等。我们还以分析电力生产商成本的构成为重点,揭示了电力生产商容量成本的本质意义,分析了充裕度市场的交易模型。探索了电力系统元件故障对用户成本中电网购电成本的影响,分析了评估元件故障对电网购电成本影响的量化计算方法。并引入电力系统元件效用风险指标至购电决策模型,建立了电力交易模型等。原规划中的故障模型存在不足,特别是在对评估市场风险和电网运行方面,本文进行深刻揭示,同时,分析了评估电力系统元件运行可靠性的新模型。这-模型充分考虑了电力系统元件的既运行环境、往检修情况和持续运行时间等因素,分析了元件故障率模型的伸缩理论等。本文还引入了可靠性调整电价的概念,并通过某一供电区域的用电情况为依据进行了案例分析,介绍了引入该电价的影响。以电力市场发展、电力系统安全稳定经济运行为背景,本文对其发展过程中可靠性领域的新现象、新不足等问题,进行了系统研究、初步分析,并探索建立了有效方法,具有一定参考价值。
[Abstract]:In recent years, with the further acceleration of the electric power market-oriented process, there are two factors that affect each other in the process of power system operation: the market and the security risk, in order to further ensure the safe and stable operation of the power system. The electricity market is well developed, we will base on the power system security and adequacy, focus on the consideration of reliability in the process of electricity trading, study its principle and mode, and provide theoretical support. This paper introduces the idea of introducing the reliability of power system into the electricity market as a kind of resource, and studies the market organization mode, market member declaration mode, trade commodity type and so on in the adequacy market. Furthermore, the trading algorithm of adequacy market is constructed. The method of single member's influence on system adequacy is preliminarily established. We also focus on analyzing the composition of power producer's cost. In this paper, the essential meaning of capacity cost of power producer is revealed, the transaction model of adequacy market is analyzed, and the influence of power system component failure on power grid purchase cost is explored. The quantitative calculation method for evaluating the effect of component faults on power purchase cost is analyzed, and the utility risk index of power system components is introduced to the power purchase decision-making model. Established the electricity transaction model and so on. The fault model in the original planning has shortcomings, especially in the evaluation of market risk and power grid operation, this paper deeply reveals, at the same time. A new model for evaluating the reliability of power system components is analyzed. The expansion theory of component failure rate model is analyzed. This paper also introduces the concept of reliability price adjustment, and analyzes the influence of the price on the basis of a case study of the electricity consumption in a power supply area. Based on the background of the development of power market and the safe and stable economic operation of power system, this paper makes a systematic study and preliminary analysis on the new phenomenon and new deficiency in the field of reliability in the process of its development. The effective method has been established and has certain reference value.
