【摘要】 本文研究大系统优化理论在混合电力系统长期发电容量发展规划中的发展和应用。文中建立了混合系统发电容量最优规划的大规模整数规划模型;提出了求解大规模混合规划的推广算法;借助于该算法,将容量规划问题分解为一个主问题和一组子问题;最优容量规划通过迭代地求解主问题和子问题组得出。通过理论分析及其对BN电力系统的实例验算,证明了所建立模型的可行性和通用性,以及所提分解算法的实用性和有效性。更多还原

【Abstract】 A Large Mixed Integer Linear Program (MILP) is established for Generation Capacity Expansion (GCE) in Hydro-Thermal Electric Power System in this paper. A decomposition algorithm to the MILP is developed. Based upon the algorithm, the capacity expansion problem is decomposed into a master problem and a set of subproblems. The solution is found by interactively solving the master problem and subproblems.Through theoretical analysis and the case study for BN power system, the feasibility and generalit yof the model are proved, the algorithm presented in the paper is practical and effective, it is a result of the development and improvement of the current methods.更多还原
