Abstract

The invention provides an intelligent community demand response scheduling method and system, and the method comprises the steps: employing the minimum total operation cost of a system and the minimumexchange electric quantity of a power grid as a target function, building an optimal scheduling model comprising photovoltaic, energy storage and electric vehicles, and carrying out the solving through employing a multi-population collaborative purification genetic algorithm, and obtaining an optimization result. The method comprises the following steps: firstly, analyzing main components of theintelligent cell, and researching the operation characteristics of the intelligent cell; For the coordinated optimization scheduling problem of the daily load demand response of intelligent power cells containing multiple energy resources, the residential intelligent power mode including distributed energy such as electric vehicles and energy storage is taken as the research object. The minimum total operation cost of a system and the minimum exchange electric quantity of a power grid are taken as objective functions, the constraint conditions of schedulable loads, electric vehicles, distributed energy storage and the like are considered, a multi-population collaborative purification genetic algorithm is used for solving, an optimization result is obtained, peak clipping and valley fillingare achieved, and finally the effectiveness of an optimization model and a solving strategy is analyzed by means of examples.

Description

technical field [0001] The invention belongs to the technical field of power grids, and relates to a demand response scheduling strategy for an intelligent community based on a multi-population co-evolutionary genetic algorithm. Background technique [0002] With the development of supporting technologies such as intelligent collection, sensing, and control, the large-scale application of intelligent communities becomes possible. In 2017, the "Intelligent Community Demonstration Project", one of the supporting projects of the national key research and development plan "Urban User and Power Grid Supply-Demand Friendly Interactive System", carried out large-scale promotion. At present, 6 intelligent communities have been completed in Wujin, Changzhou and Jinji Lake, Suzhou. , mainly for the construction of resident user interaction capabilities, the construction of photovoltaic storage in public areas of communities, and electric vehicles. As a key component of smart communit...
