Problems solved by technology

[0004]As an extension of electricity demand response in the context of multi-energy complementarity, integrated demand response provides an entry point for the interaction between supply and demand of integrated energy, and the flexible scheduling of demand response is very Affected by the price mechanism to a large extent, most of the existing research is to solve the problem of demand response resource allocation under a single or fixed energy price, and there is little research on the flexible formulation of multi-type energy prices

Abstract

The invention discloses a scheduling method of an electric heating multi-energy energy supply system. The scheduling method comprises the steps of acquiring multi-energy system parameters and energy center related parameters; establishing a target function by maximizing the obtained income, and determining a multi-energy system optimization model; determining an energy center optimization model bytaking the minimum energy purchase cost as a target function; converting the energy center optimization model into a KKT optimal condition as a constraint condition of the multi-energy system optimization model; carrying out relaxation and convexity processing on the multi-energy system optimization model; for the multi-energy system optimization model after relaxation and convexity processing, solving a second-order cone rule problem to obtain an iterative initial point; and iteratively solving a second-order cone rule problem, and if the second-order cone rule problem meets a convergence condition, outputting an optimal solution. On the premise of considering the benefits of both supply and demand sides, a reasonable energy price is formulated, and a day-ahead scheduling scheme and an energy configuration structure are optimized.

Description

technical field [0001] The present application relates to the technical field of electric power dispatching, in particular to a dispatching method of an electric thermal multi-energy energy supply system. Background technique [0002] As a new form of power system under the background of energy transformation, the multi-energy system is aimed at optimizing the energy structure on the supply side and complementing the advantages of various energy sources on the demand side, so as to effectively improve energy utilization and alleviate environmental pollution. And other issues. [0003] As an important participant in the multi-energy system, users can actively adjust energy consumption according to differences in energy prices at different times, improve the consumption level of clean energy, and smooth system load fluctuations. This is of great significance for the economically stable operation of the multi-energy system. As the main form of interactive response between user...
