Abstract

The invention provides a power flow optimization method for a cold-heat-electricity integrated energy system. The power flow optimization method comprises the following steps: A, constructing a planning construction cost minimum objective function for the cold-heat-electricity integrated energy system; b, establishing an electric power system constraint model, a heat supply system constraint model, an energy station constraint model and a cold force load power constraint model as constraint conditions of the minimum objective function of the planning and construction cost; and C, solving the objective function with the minimum planning and construction cost according to the constraint conditions in the step B. According to the power flow optimization method for the cold-heat-electricity integrated energy system, load power balance of cold, heat and electricity and stable operation of the system can be met, it can be guaranteed that the overall planning cost of the system is minimum, and a basis is provided for achieving optimized operation of the system and the maximum economic benefit.
