电力-天然气集成能源系统的统一规划模型与Benders解耦方法
Unified Planning Model of Integrated Electric Power and Natural Gas Energy Systems Based on Benders Decomposition
摘要
Abstract
In recent years, with the ever-increasing penetration of natural gas generation in actual power systems, it is necessary to consider the impacts of the natural gas systems on the planning and operation of the concerned power systems.Meanwhile, the interconnection of multiple energy sources represents one of the development trends of future energy systems.Hence, unified planning and operation of a power system and a natural gas system concerned are important issues to be addressed.Given this background, based on the steady-state gas flow model of natural gas systems, this paper preliminarily studies the unified planning of integrated electricity and natural gas energy systems.Firstly, we study the unified planning problem of integrated electricity and natural gas energy systems considering the boundary conditions of the electric power system and natural gas system, so as to optimally determine the locations and capabilities of natural gas-fired plants, transmission lines, natural gas supply stations and natural gas pipelines, and construct a mixed integer nonconvex nonlinear programming model (MINNPM).Then, we adopt the Benders decomposition algorithm to simplify the presented MINNPM into a two-level optimization framework including master and sub problems, which can be iteratively solved respectively by the commercial CPLEX and IPOPT solvers.Finally, we establish an integrated electricity and natural gas energy system including a 54-node power system and 19-node natural gas network to demonstrate the feasibility of the developed unified planning model based on Benders decomposition.关键词
