Domestic intelligent microgrid optimization configuration method

Abstract

The invention discloses a domestic intelligent microgrid optimization configuration method. The method comprises the steps of analyzing actual conditions of local wind and solar energy resources; performing investigation and survey on domestic load electricity consumption data; determining types and capacity limit of distributed power supplies, and types of inverters and controllers of the domestic intelligent microgrid; taking the lowest total operating cost of the domestic intelligent microgrid as an optimization target function; setting constraint conditions for the domestic intelligent microgrid to satisfy requirements of domestic load on power quality and technology; performing an artificial bee colony optimization algorithm; and outputting an optimization result with the lowest target function value and obtaining a configuration scheme. According to the domestic intelligent microgrid optimization configuration method, the artificial bee colony algorithm is applied to the optimization configuration of the domestic intelligent microgrid, so that the optimization speed is relatively high and the working efficiency is improved; a collector for sampling the domestic load electricity consumption is designed based on LABVIEM virtual instrument visual software, so that the domestic load electricity consumption can be monitored and sampled in real time, and the peak-valley periods of electricity consumption can be observed, so that evidence can be provided for realizing reasonable load access.

Description

technical field [0001] The invention relates to the optimal configuration method of a micro-grid, in particular to a method for optimal configuration of a home-style smart micro-grid. Background technique [0002] The home-style smart microgrid is an autonomous system that can realize self-control, protection and management. According to whether it is connected to the mains, the home-style microgrid can be divided into two types: grid-connected and independent. [0003] At present, there are few studies on the optimal configuration of household microgrids. Most of the research is on the optimal configuration of tens of kilowatts to megawatts, and most of them are on the optimal configuration of distributed power capacity. The more typical software for researching the optimal configuration of grid-connected microgrids is the HOMER software developed by the National Energy Laboratory of the United States. This software provides users with two types of operation schemes. The m...

Problems solved by technology

[0004] The above-mentioned optimal configuration method is carried out under the fixed operation mode provided by the software, but the actual home smart microgrid will encounter many complicated situations, such as small load capacity, insufficient or excessive light, wind power, etc. Too large or too small, sudden changes in household load power consumption, etc. will change the operation mode

Therefore, the above method is not suitable for optimal configuration of household smart microgrid

In addition, the random search speed is slow, and when the operating conditions change, the accuracy of the optimization will also be affected, which will eventually lead to a certain deviation in the final optimal configuration plan
