Abstract

The application relates to a method, device and apparatus for jointly dispatching an offshore wind farm and island micro-grids. The method includes: acquiring a first predicted power and a second predicted power; obtaining the sum of the first predicted power and the second predicted power to obtain the predicted total power of the offshore wind farm and various island micro-grids; reporting the operating state information and the predicted total power of the offshore wind farm and the respective island micro-grids to a grid dispatching system; receiving the dispatching power generated by thegrid dispatching system based on the operating state information and the predicted total power; and performing the dispatching control of the generated power of the offshore wind farm and the island micro-grids according to the dispatching power . The method predicts the total power of an offshore wind farm and island micro-grid joint power supply system, and achieves the joint dispatching of theoffshore wind farm and island micro-grid joint power supply system in conjunction with the power grid dispatching system, greatly reduces the number of grid scheduling objects, and improves the dispatching efficiency.

Description

technical field [0001] The present application relates to the technical field of power grid dispatching, in particular to a joint dispatching method, device and equipment for offshore wind farms and island microgrids. Background technique [0002] With the development of modern power grid technology, offshore wind farms and island microgrids have changed from separate construction and operation in the past to the current joint construction to form a combined power supply system for offshore wind farms and island microgrids. The joint generation and power supply system of offshore wind farms and island microgrids considers the construction of offshore wind farms and the power supply of islands as a whole, uses the submarine cable transmission network of offshore wind farms to connect islands with mainland power grids, and simultaneously builds island microgrids. Island microgrids usually use wind power, photovoltaics, diesel generators (or micro gas turbines) and energy stora...
