Electric power virtual energy storage control system and method

Abstract

The invention discloses an electric power virtual energy storage control system and method. The electric power virtual energy storage control system comprises an electric power system, a power network power load control energy management system, a front communication server, a 0.4KV distribution network communication system, a 0.4KV power network, an electric energy meter, an electric energy meter electricity utilization parameter forwarding device, a power line carrier electricity utilization parameter receiving and electricity utilization load staggering peak control device and electricity utilization loads. A consumer side control device selects the staggering peak control mode of the electricity utilization loads according to electricity utilization information issued by the electric power system and the intention of an electric power consumer, so that the load control of power network peak load shifting is in the best state, the difference between the peak load and the trough load in operation of the power network is reduced, and the energy conservation and consumption reduction purpose of virtual energy storage is achieved; the electric power system issues electricity utilization information to the electric power consumer side control device according to the peak and trough time periods and electricity utilization parameters formulated through optimization of a power network load curve so as to control part of electric equipment in a staggering peak mode, the electricity consumption during the trough period of the power network is increased, and the electric power virtual energy storage control in the mode of peak load shifting is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power storage, and in particular relates to a system and method for electric virtual energy storage control. Background technique [0002] At present, the world's known power energy storage technologies mainly include physical energy storage (such as pumped water storage, compressed air energy storage, flywheel energy storage, etc.), electrochemical energy storage (such as sodium-sulfur batteries, flow batteries, lead-acid batteries, nickel-cadmium batteries, supercapacitors, etc.) and electromagnetic energy storage (such as superconducting electromagnetic energy storage, supercapacitors, etc.). We know that physical energy storage is a relatively mature energy storage method in the world and an early practical application. Its energy conversion efficiency can reach about 70-75%. However, due to terrain and geological conditions, it does not have a large Prospects for large-scale promotion and a...
