Abstract

The invention relates to a micro-grid power supply and a monitoring method. According to the monitoring method, generated power of a photovoltaic module and a wind power module of a micro-grid can be predicted, the change situation of loads is predicted, based on the energy storage condition, detected in real time, of a storage battery module and the running condition, obtained in real time, of a large grid, a power supply strategy is formulated, and therefore the micro-grid can be in a safe and economical running state making users satisfied.

Description

Technical field [0001] The invention relates to a microgrid power supply and monitoring method. Background technique [0002] As the global energy crisis continues to increase, low-carbon, clean renewable energy has become a research hotspot. At present, countries around the world have carried out research projects on micro-grids containing renewable energy. Microgrid refers to a network composed of multiple distributed power sources and their related loads according to a certain topology, and is connected to the conventional power grid through static switches. [0003] A large number of wind / solar distributed power generation is connected to the low-voltage distribution network as a two-way dispatchable unit in the form of a microgrid, forming a microgrid group or an active distribution network composed of multiple microgrids. However, due to the high randomness of renewable power sources such as wind power and photovoltaic power generation, the uncertainty of clean power ...
