Distributed photovoltaic source network load energy storage flow control method

Abstract

The invention relates to a distributed photovoltaic source network load energy storage flow control method. According to the method, monitoring data is transmitted to an upper computer through an Internet of Things technology through a photovoltaic panel monitoring part, an inverter monitoring part, an energy storage battery monitoring part, a grid-connected power transmission line monitoring part and a control part, so that the operation state of the distributed photovoltaic power station can be remotely monitored, and the method is of great significance to distributed photovoltaic operation and maintenance. According to an electric energy curve and a load curve generated by a photovoltaic panel, the distributed photovoltaic 'source network load storage' energy flow control method can be used reasonably store electric energy in an energy storage battery and / or grid connection, so that bidirectional ordered flow of energy is realized, the purpose of reasonably utilizing distributed photovoltaic power generation energy is achieved, peak load shifting is achieved, distributed photovoltaic is consumed, generation efficiency is improved. and the phenomenon of light abandoning is reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic power station energy flow control, in particular to a distributed photovoltaic source network load storage energy flow control method. Background technique [0002] In recent years, with the extensive construction of distributed energy systems with a high proportion of renewable energy, new energy entities characterized by decentralization will become an important part of the electricity market, and the "carbon peak" and "carbon neutral" It is proposed that it is urgent to build a new power system with the theme of new energy. Distributed photovoltaic power generation is a good choice. It is clean, low-carbon, safe, and efficient, and can be widely used in industrial parks and residential buildings. It can be used in rural areas, pastoral areas, and mountainous areas. Large, medium, and Built near small cities or business districts to meet the electricity demand of local users. Distributed photovolta...

AI Technical Summary

Problems solved by technology

Distributed photovoltaics are often scattered and installed on the roof, unmanned monitoring, fault warning and operation and maintenance are very necessary; at the same time, photovoltaic power generation systems are random and volatile, and the mismatch between "source" and "charge" has led to many photovoltaic systems. The electric energy cannot be effectively absorbed, and there is a certain degree of "abandoned light" phenomenon
