Embodiment Construction

[0021] 1. Characteristics of distributed power generation and regional load

[0022] 1. Characteristics of distributed power supply:

[0023] Based on the differences in the power output characteristics of each DG, DGs are divided into three categories: random power DGs, controllable power DGs, and energy storage devices. Random power type DG (such as DG generated by renewable energy such as wind energy and solar energy) is affected by energy and weather conditions, and the output power is highly random; controllable power type DG (such as diesel engine, micro gas turbine, etc.), output power is stable, And the control of the output power can be realized through the adjustment of the fuel system; the energy storage device (such as battery, supercapacitor, flywheel energy storage, etc.) is used as the energy buffer of the microgrid, and the power can be quickly adjusted according to the need.

[0024] First analyze from four aspects: economy, voltage quality, power supply reli...

Abstract

The invention relates to a distributed power supply and region load matched feature matching method. Feature analysis is conducted on different region loads and standby distributed power supplies, all feature values are quantified according to a uniform scale, close degree calculation is conducted on the close degree between the feature values, the adaptability of the standby distributed type power supplies and the adaptability of the region loads are matched through feature matching, and the obtained result can provide guidance for optimization of the distributed power supplies in different load regions. The method is relatively accurate and visual, a reasonable matching scheme can be provided by comprehensively taking various conditions and limiting factors into consideration, the advantages of the distributed power supplies can be brought into full play to the maximum while reliable electricity utilization of the loads is ensured, and the comprehensive benefits of a micro-grid are maximized.

Description

Technical field [0001] The invention involves a distributed power supply system, which specializes in a feature matching method that is compatible with the regional load. Background technique [0002] The penetration of distributed power supply (DG) in the distribution grid has continued to increase, and the impact of DG on load is more serious.The access to the proper form of the load side can be used as a strong support for the large power grid to significantly improve the power supply capacity of the system; and the inappropriate DG access will have many adverse effects, and even cause inestimable losses to important loads.Different distributed power supplies have different characteristics, and different types of loads have different requirements for economic, power quality, and power supply reliability. What DG is installed in different load areas to fully use the advantages of DG and ensure the economic stable operation of loadEssence [0003] At present, many scholars have ...
