【摘要】：随着经济的快速发展,越来越多的环境污染受到人们的重视,具有保护环境和不消耗燃料特征的风电被看作是最有前途的可再生能源之一。中国政府已经出台了许多政策促进风电的发展。然而,风电与常规能源不同的间歇性和不可预测的特性对风电并网后的调度模式提出了挑战。 近年随着中国风电的快速发展,如何整合调度更多风电进入电网,以及如何在减少温室气体排放量和增加经济成本的冲突之间做好平衡,并相应地调整调度模式成为一个很大的挑战。 本文首先研究了边际成本理论和外部性理论,并以电力体制改革为分界线,研究了西方发达国家在电力体制改革前后的调度模式和经验启示,同时研究了中国电力调度的发展过程,得出调度方式从垄断的一体化垂直管理调度体制转向了市场竞争调度管理体制应该是历史发展的趋势。 其次,本文重点分析了中国的联合调度存在的三种实际情况,第一,因为中国的电源结构仍以火电为主,所以为了深度调峰,有可能需要机组启停调峰。第二,越来越多的火电机组成为热电联产机组,而为了保障供热,不可能减少热电联产机组的出力,更不可能对热电联产机组实施停机,所以必须考虑不停机情况下的调度情况。第三,水电并不能恒定出力,甚至部分地区没有水电,所以在调度模型的构建中也必须充分考虑水电不参与调度的情况。因此依据中国的实际情况,建立了含风电的经济环境联合调度模型。为了求解模型,本文利用了GAMS软件平台。GAMS是专门为线性规划、非线性规划、混合整数规划、混合整数非线性规划等优化问题而设计的软件平台, 最后,本文以东北电网辽宁省的为算例,模拟计算了四种情况下含风电的经济环境联合调度模型的结果,结果显示风水火联合调度比单独的水火电调度在环境保护方面更优,并且说明了一个相对较好的环境改善,可以在一个相对较低的经济损失下完成。
[Abstract]:With the rapid development of economy, more and more people pay attention to environmental pollution. Wind power, which has the characteristics of protecting environment and not consuming fuel, is regarded as one of the most promising renewable energy sources. The Chinese government has introduced many policies to promote the development of wind power. However, the intermittent and unpredictable characteristics of wind power and conventional energy have challenged the scheduling mode of wind power grid. With the rapid development of wind power in China in recent years, how to integrate and dispatch more wind power into the grid, and how to strike a balance between reducing greenhouse gas emissions and increasing economic costs, It is a great challenge to adjust the scheduling mode accordingly. In this paper, the marginal cost theory and the externality theory are studied, and the dispatch mode and experience of the western developed countries before and after the electric power system reform are studied with the electric power system reform as the dividing line. At the same time, the development process of electric power dispatching in China is studied, and it is concluded that it is the historical development trend that the dispatching mode has changed from the monopolistic integrated vertical management dispatching system to the market competitive dispatching management system. Secondly, this paper focuses on the analysis of the three actual conditions of China's joint dispatch. Firstly, because the power supply structure of China is still dominated by thermal power, it may be necessary to start and stop the peak-shaving for the sake of deep peak-shaving. Second, more and more thermal power units have become cogeneration units. In order to ensure heat supply, it is impossible to reduce the output of cogeneration units, let alone to shut down cogeneration units. Therefore, we must consider the scheduling situation without downtime. Thirdly, hydropower can not make a constant contribution, even in some areas there is no hydropower. Therefore, in the construction of dispatching model, the situation that hydropower does not participate in dispatching must be fully considered. Therefore, according to the actual situation in China, the combined economic environment scheduling model with wind power is established. In order to solve the model, GAMS software platform is used in this paper. GAMS is a software platform specially designed for linear programming, nonlinear programming, mixed integer nonlinear programming and other optimization problems. Taking Liaoning Province of Northeast Power Grid as an example, this paper simulates and calculates the results of the combined dispatching model of economic environment with wind power under four conditions. The results show that the combined dispatching of wind, water and fire is better than that of hydro-thermal power dispatching alone in terms of environmental protection. It also shows that a relatively good environmental improvement can be achieved under a relatively low economic loss.
