【摘要】：全球的能源问题越来越突出,成为限制经济发展的一大因素,如何有效利用风能、太阳能、水能等清洁可再生的能源也越来越被人们重视。风光水互补发电系统利用三种能源的互补性使系统功率输出更加稳定。另外,储能系统凭借其可充可放的运行特性,能有效克服可再生能源发电系统的不确定性。首先,本文提出了风光水互补发电系统的调度策略,力求对上述系统的稳定、经济运行做出贡献。在综合考虑了投资、系统运营成本、环境治理等因素,以及孤网、并网两种运行方式的前提下,本文首先建立了最低成本的优化模型。在此基础上,进一步提出了风光水互补发电系统的调度策略,实现了三种新能源输出功率的最佳配置。最优运行和调度策略可以评估系统在不同运行方式下的经济性能,提高互补系统的可靠性和灵活性。再次,本文提出了一种基于场景优化的储能优化调度及安全约束机组模型。目的在于使能耗最小化,并满足电网安全约束、做好储备计划以及调度约束方案。另外,风力波动的不确定性是通过蒙特卡洛仿真和拉丁超立方体技术来模拟的。之后我们利用一种可计算的、混合整数线性规划算法来有效的解决模型问题。最后,我们用IEEE3机6节点和10机39节点系统来对这种模型进行测试,其结果能够对所提出的模型在获得优化储能能力、经济调度和机组组合等方面进行阐述。最后,本文新能源互补运行和储能优化调度进行了总结和展望。
[Abstract]:Global energy problems are becoming more and more prominent and become a major factor restricting economic development. How to effectively utilize clean and renewable energy such as wind energy solar energy and water energy has been paid more and more attention. The wind-water complementary power generation system makes the system power output more stable by utilizing the complementarity of three kinds of energy sources. In addition, energy storage system can effectively overcome the uncertainty of renewable energy generation system with its rechargeable and rechargeable operating characteristics. First of all, this paper puts forward the dispatching strategy of the wind-water complementary power generation system, in order to make a contribution to the stability and economic operation of the system mentioned above. On the premise of synthetically considering the factors of investment, system operation cost, environmental treatment, and two operation modes of isolated network and connected network, this paper first establishes the optimization model of the lowest cost. On this basis, the scheduling strategy of the wind-water complementary power generation system is put forward, and the optimal configuration of the output power of three new energy sources is realized. The optimal operation and scheduling strategy can evaluate the economic performance of the system under different operation modes and improve the reliability and flexibility of the complementary system. Thirdly, this paper presents an optimal scheduling and security constrained unit model based on scenario optimization. The purpose of this paper is to minimize energy consumption and meet grid security constraints. In addition, the uncertainty of wind fluctuation is simulated by Monte Carlo simulation and Latin hypercube technology. Then we use a computable mixed integer linear programming algorithm to solve the model problem effectively. Finally, we test this model with IEEE3 6-bus and 10-machine 39-bus systems. The results show that the proposed model can obtain the optimal energy storage capacity, economic scheduling and unit combination. Finally, this paper summarizes and prospects the complementary operation of new energy and optimal scheduling of energy storage.
