Abstract

The invention discloses a demand side response-based microgrid optimal unit and time-of-use electricity price optimization method, which comprises the following steps: (1) acquiring supply and demandhistorical data of a microgrid, including internal load data of the microgrid, a supply situation of distributed regenerable energy and basic information of all types of energy supply units; (2) analyzing outputs of all energy supply systems by using the historical data so as to analyze a supply and demand situation in the microgrid; (3) setting an optimized target function subjected to distributed optimization; (4) performing optimized solving by using a particle swarm search algorithm and an interior point method. According to the demand side response-based microgrid optimal unit and time-of-use electricity price optimization method disclosed by the invention, the supply situation of the regenerable energy of the microgrid and a demand side response under the excitation of time-of-use electricity price are organically combined, and an optimal unit combination of the microgrid and a time-of-use electricity price strategy are subjected to the distributed optimization through the particle swarm search algorithm and the interior point method, so that the problems of extremely high operation cost of the microgrid and too large lack of internal loads are effectively relieved, and the electricity use demand of a user can be 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 ...
