Abstract

The invention discloses a microgrid energy management method and a system thereof. The microgrid energy management system comprises a super-capacitor energy storage management module, a grid-connected energy storage management module, an off-grid energy storage management module and an off-grid power generation and load management module. An energy management module operates based on difference between generation power and load power in a microgrid, a super-capacitor energy storage management module enables a high-frequency part in power difference values in the microgrid to be contained in a power set value of a super capacitor to the maximum extent, the grid-connected energy storage management module sets powers of all stored energy in the microgrid according to a stored energy surplus capacity weighting allocation algorithm and a stored energy charging and discharging power set curve, the off-grid energy storage management module sets other stored energy except main stored energy according to the charging and discharging power curve, and the off-grid power generation and load management module controls power source and load in the micro grid according to a grid-connected management strategy or an off-grid management strategy.

Description

technical field [0001] The invention belongs to the field of new energy power generation, and in particular relates to a microgrid energy management method and a system thereof. Background technique [0002] The global energy crisis and environmental problems have promoted the rapid development of renewable energy power generation. While improving the energy structure, renewable energy power generation also introduces some technical problems, among which the research on grid access issues has formed the distributed generation (DG) research field. The flexible and decentralized DG location is well suited to decentralized power demand and resource distribution, delaying the huge investment required for transmission and distribution network upgrades. Due to natural conditions, it lacks the characteristics of flexibility and controllability, and is an uncontrollable source for large power grids. Large power grids take isolation and restriction measures for DG, which limits the...
