Cooperative game-based multi-park energy scheduling optimization method for comprehensive energy system

Abstract

The invention relates to an integrated energy system multi-park energy scheduling optimization method based on a cooperative game. The method comprises the following steps: 1), obtaining an integratedenergy system structure comprising multiple parks, and obtaining electric energy transaction modes between the parks and a power distribution network and between the parks; 2) constructing a multi-park energy scheduling cooperative game optimization model according to the comprehensive energy system equipment output model and the park operation cost model; and 3) solving the multi-park energy scheduling cooperative game optimization model to obtain an optimal scheduling scheme of the comprehensive energy system. Compared with the prior art, the method has the advantages that the energy utilization rate is increased, the energy supply pressure is relieved, and the park daily operation cost and the power grid load peak-valley difference are reduced.

Description

technical field [0001] The invention relates to the field of integrated energy system control, in particular to a cooperative game-based multi-park energy dispatch optimization method for an integrated energy system. Background technique [0002] The capacity of a single park is limited. By forming a park interconnection system, that is, sharing the load and sharing the spare capacity with adjacent parks, it has the benefits of enhancing system reliability, expanding the scope of power supply, and increasing the rate of new energy consumption. However, most of the existing studies only optimize the electric energy of multiple parks, ignoring that in the comprehensive energy market, various energy sources such as cold, heat, and gas can also be classified into the broad demand-side resource category and participate in energy transactions. In order to realize the collaborative optimization of the integrated energy network. [0003] The development of various energy storage te...

However, most of the existing studies only optimize the electric energy of multiple parks, ignoring that in the comprehensive energy market, various energy sources such as cold, heat, and gas can also be classified into the broad demand-side resource category and participate in energy transactions. In order to realize the collaborative optimization of the integrated energy network

[0003] The development of various energy storage technologies has promoted the consumption of new energy. Among the existing storage methods of wind energy, except for pumped storage, there are problems such as limited storage capacity, insufficient economy, and inability to use large-scale applications. Due to the power-to-gas (P2G The development of technology can realize large-scale storage of electric energy in the form of natural gas, and the coupling effect of various forms of energy in the stages of production, transmission, and use is becoming stronger and stronger. At present, the research on the integrated energy system of electrothermal coupling is very comprehensive. However, there are few studies on electricity, heating, cooling, and integrated energy systems. In the existing park integrated energy scheduling methods, the utilization rate of energy is not high, and the optimal resource allocation cannot be achieved.
