Optimization method of optimal unit and time-of-use electricity price in microgrid based on demand-side response

Abstract

The invention discloses a method for optimizing micro-grid optimal unit and time-of-use electricity price based on demand side response, including steps: 1) Acquiring historical data of supply and demand of micro-grid, including internal load data of micro-grid, supply of distributed renewable energy 2) Use historical data to analyze the output of each energy supply system, and analyze the supply and demand inside the microgrid; 3) Set the optimization objective function for decentralized optimization; 4) Use the particle swarm search algorithm and interior point method for optimization. The present invention organically combines the energy supply situation of microgrid renewable energy and the demand side response under the incentive of time-of-use electricity price, and uses the particle swarm algorithm and interior point method to disperse and optimize the optimal unit combination and time-of-use electricity price strategy of the microgrid, thereby effectively Alleviate the problems of high operating cost and excessive internal load shortage of the microgrid, and ensure that the electricity demand of users is well met.

Description

technical field [0001] The present invention relates to the technical field of micro-grid optimal unit combination and time-of-use electricity price optimization, in particular to an optimization method for micro-grid optimal unit and time-of-use electricity price based on demand side response. Background technique [0002] As of the end of 2017, with the advancement of my country's electricity market reform and the accompanying launch of incremental distribution networks, microgrids, as an actual operating mode of incremental distribution networks, have received high attention and attention from all walks of life. As a reliable form to solve the local consumption of new energy and improve the consumption rate of new energy, micro-grid's efficient and safe operation is the key content that needs to be concerned about in the construction of micro-grid. [0003] In the operation process of the microgrid, first of all, for the energy supply side, part of the power supply comes ...
