Distributed generation intelligent monitoring system

Abstract

The invention relates to a distributed generation intelligent monitoring system. The intelligent monitoring system can predict the generated power of a photovoltaic module and a wind power module of distributed generation, and the changes of loads and implement the optimal control strategy on the basis of the energy storage conditions of a storage battery module, the running conditions of a diesel generator and the running conditions of a power distribution network, wherein the storage conditions of the storage battery module and the running conditions of the diesel generator are detected in real time, and the running conditions of the power distribution network are obtained in real time.

Description

Technical field [0001] The invention relates to a distributed power supply intelligent monitoring system. Background technique [0002] With the development of the economy, the demand for electricity has grown rapidly, and the scale of the power grid has continued to expand. The disadvantages of the ultra-large-scale power system have become increasingly prominent: poor operational stability, difficulty in adapting to users' requirements for power safety and reliability, and diversified power supply needs. [0003] Distributed generation (distributed generation, DG) is a new type of electric energy, including photovoltaic power generation system, wind power generation system, micro gas turbine power generation system, etc. Distributed power generation technology has a series of advantages such as environmental protection and economy, and can well meet people's requirements for power safety, stability and economic environmental protection. It has attracted widespread attentio...

Problems solved by technology

[0004] However, fundamentally speaking, these small-scale renewable energy power generation methods have shortcomings such as small capacity, low product efficiency, poor power supply reliability, and high power generation costs, which greatly hinder the large-scale application and further development of this type of power generation system.

[0005] In addition, the access of DG to the distribution network also brings new problems and challenges to the protection and control of the distribution network

Photovoltaic and wind power energy is an intermittent energy source, and it is inevitable that the power generation will fluctuate with the intensity of sunlight and the intensity of wind during grid-connected operation.

Therefore, the access of distributed power generation with a high penetration rate to the distribution network will inevitably bring many negative effects to the operation, scheduling and management of the distribution network.
