1、电力市场论文：市场条件下电网备用容量的分配【中文摘要】我国经济的快速发展和人民生活水平的提高,要求电力行业适应经济和社会的发展步伐,顺应时代发展的潮流,努力提高供电质量和水平。电力系统中充足的备用容量是保证供电可靠性的重要前提,在市场环境下应逐步脱离传统备用容量的分配方法寻求一种以提高经济效益为目标的分配方法。本文主要讨论了在市场条件下备用容量分配的两种途径,即只考虑发电侧备用容量的分配方法和可中断负荷参与备用容量的分配方法。首先分析了备用容量的分类形式、成本组成和效益分析,提出备用容量作为商品在市场上进行交易;并以社会效益最大
2、为目标函数,分析了只考虑发电侧备用容量的分配方法并建立了优化模型,通过算例验证了该方法与传统的方法相比更加优越;建立了可中断负荷参与备用容量的分配模型,并给出了各个模型的适用范围及分析了其优缺点,进一步建立了可中断负荷和发电侧备用两者的联合优化模型;在保持相同电网可靠性的情况下,该模型可使电网公司购买备用容量的成本最小。通过该论文的分析研究,在市场环境下应该以经济手段对备用容量进行分配,这不仅可以使备用资源得到充分利用,还可以使经济效益得到优化。【英文摘要】Rapideconomicdevelopmentandtheliving
