电力市场论文：市场条件下电网备用容量的分配.doc

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

2、,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】Rapid economic development and the living standards improvement requires us to follow the power indus

3、try should the pace of economic and social development, follow the trend of the times, efforts to improve the quality and level of supply. The power industry should follow economic and social development pace and the trend of the times, made efforts to improve the quality and level of electricity. R

4、eserve capacity is an important guaranty to ensure reliability of power supply, in the market environment, it should gradually break away from The traditional allocation of reserve capacity and gradually find a goal which could improve the economic efficiency of reserve allocation.This article discu

5、sses, the two ways in reserve allocation in the market conditions, which are only considering the generation side of the spare reserve allocation and Interruptible load to participate in the reserve capacity allocation. Firstly, this article analyzed the classification form of spare capacity, compos

6、ition and cost-benefit analysis, concluded that reserve capacity can be traded as a commodity in the market. And then analysis the optimization model of only consider the generation side of the reserve capacity, to the maximum social benefit as the objective function, obtained through an example tha

7、t the method has superior economic compared with the traditional method. Finally, analyzed the model of interruptible load to participate in the reserve capacity allocation, and analyzed the scope of each model and the advantages and disadvantages. Established optimization model which join Interrupt

8、ible load and standby generation side together, this model made grid companies to purchase reserve allocation in the minimum cost. Through a model validated that in the same case of the grid reliability, the cost of purchasing reserve of integrated optimization model is less than the other two ways.

9、By the argument of the paper can be drawn that, in the market environment, economic instruments should be assigned to allocate the reserve, this is not only made the resources of reserve allocate in a rational way, but also could optimize the economic benefits.【关键词】电力市场 备用容量 可中断负荷 优化分配 社会效益【英文关键词】po
