Energy control method, apparatus, energy management system, and storage medium

Abstract

The invention provides an energy control method, a device, an energy management system and a storage medium, which relate to the technical field of energy control. The method comprises the following steps: judging whether a power generation system can be connected with a public power grid based on a preset grid-connection judgment rule; determining whether the power generation system can be connected with a public power grid based on the preset grid-connection judgment rule; If so, the control power generation system transmits power to the public power grid based on the preset constant power grid-connected mode, so as to transmit power of constant power to the public power grid; If not, the control generation system is not grid-connected with the public grid, and the load is supplied basedon a preset non-grid-connected power supply strategy. The energy control method, the device, the energy management system and the storage medium of the invention can realize the efficient utilizationof the energy when not connected to the grid, can realize the efficient dispatch of the energy when connected to the grid combined with the constant power connection mode, and can realize the efficient operation of the inverse power control and the energy dispatch.

Description

technical field [0001] The invention relates to the technical field of energy control, in particular to an energy control method and device, an energy management system and a storage medium. Background technique [0002] The existing energy management system includes a photovoltaic power generation system, a public power grid and a load circuit, and the photovoltaic power generation system and the public power grid are connected in parallel to jointly supply power to the load circuit. When the output power of the photovoltaic power generation system is less than the power consumption of the load circuit, the public grid supplies power to the load circuit, and when the power output of the photovoltaic power generation system is greater than the power consumption of the load circuit, the excess power may be reversely sent to the public grid Electricity, causing reverse flow, will cause instability of the public grid and generate harmonic pollution. At the same time, photovolta...

AI Technical Summary

Problems solved by technology

If the connection between the photovoltaic power generation system and the public power grid is immediately cut off, all the power will be supplied to the load circuit by the public power grid at this time. Disconnecting some of the switches of the photovoltaic power generation system may also cause the public grid to output a large power supply to the load circuit

Therefore, both the current two step-by-step power regulation methods cause waste of electricity generated by the photovoltaic power generation system, and the scheduling of energy is low.
