【摘要】：电转气技术的出现为消纳风电等可再生能源的富余发电出力提供了新的途径。目前电转气厂站的投资和运行成本较高,因而单独投资建设电转气厂站的经济性就较差。在此背景下,以可再生能源(风力)发电公司为投资主体,探索风电场和电转气厂站的协同投资建设模式,建立风电场和电转气厂站的协同选址规划模型。首先,考虑电转气技术的特征,建立电转气厂站的数学模型。然后,以最大化投资净收益为优化目标,建立基于场景分析的协同选址规划数学模型,计及了电力系统和天然气系统的相关约束。在场景优化中,以历史风速时间序列为原始场景,引入一种密度聚类算法对众多历史数据进行聚类分析,以提高求解效率,从而缩减风电场出力场景。最后,采用AMPL/BONMIN求解器对所构建的风电场和电转气厂站的协同选址规划优化模型进行求解,并以修改的IEEE 39节点电力系统和比利时20节点天然气系统所构成的电力和天然气互联系统为例,说明了所提方法的可行性和有效性。
[Abstract]:The emergence of electropneumatic technology provides a new way to absorb the surplus power of renewable energy such as wind power. At present, the investment and operation cost of the power to gas plant is relatively high, so the economic efficiency of the construction of the electricity to gas plant station alone is poor. Under this background, taking renewable energy (wind) power generation company as the main investment body, the cooperative investment construction model of wind farm and power to gas plant station is explored, and the cooperative location planning model of wind farm and electricity to gas plant station is established. Firstly, considering the characteristics of electropneumatic technology, the mathematical model of EPS station is established. Then, with the goal of maximizing the net income of investment, the mathematical model of collaborative location planning based on scenario analysis is established, taking into account the constraints of power system and natural gas system. In the scene optimization, a density clustering algorithm is introduced to analyze many historical data in order to improve the efficiency of solving and reduce the wind farm output scene by taking the historical wind speed time series as the original scene. Finally, the AMPL/BONMIN solver is used to solve the optimal model of cooperative location planning for wind farm and electrically rotating gas plant. The feasibility and effectiveness of the proposed method are illustrated by an example of the power and natural gas interconnection system composed of the modified IEEE 39-bus power system and the Belgian 20-bus natural gas system.
