Abstract

The invention discloses a grid connection solution of a distributed photovoltaic and biomass power generation. Grid connection control is performed on a power grid public network, a biomass power generation system and a photovoltaic power generation system, and control and regulation are performed using photovoltaic power generation to the greatest extent, the power grid for supplementation and biomass power generation as backup, thereby realizing electric energy output; and all control and regulation commands are sent out through a monitoring master station, the monitoring master station analyzes power generation and supply situations and determines an running mode according to collected power generation system parameter information and an electrification situation of the power grid, issues the mode to a coordination controller, and the coordination controller executes the running mode. The grid connection solution of distributed photovoltaic and biomass power generation is suitable for grid connection of multiple power supplies in a rural area, and enables biomass power generation and photovoltaic power generation to run coordinately, thereby giving full play to maximum benefits and value, and meeting an environment-friendly modern energy utilization requirement.

Description

technical field [0001] The invention relates to the technical field of distribution network automation, in particular to a grid-connected solution for distributed photovoltaic and biomass power generation. Background technique [0002] Distributed power is an important part of the smart grid. It utilizes abundant biogas resources in rural areas and other biomass energy and photovoltaics to construct rural distributed power, and builds a distributed power generation system in accordance with the method of "spontaneous self-use, surplus on the grid, and grid regulation". Promote the sustainable, low-carbon and healthy development of the new rural economy. In order to better provide first-class high-quality services for customers, especially those in rural areas, and at the same time strengthen the information construction of power supply enterprises, improve intelligent service methods, and respond to the call of the country for energy conservation and emission reduction, we p...
