Problems solved by technology

[0004] After research, the inventor found that when the electric-gas coordinated control method in the prior art is applied to the electric heating and gas heating combined cycle water heating system, the phenomenon of total thermal power fluctuation is prone to occur, that is, the water cannot be heated at present. Better constant temperature control of water temperature in the system

Abstract

The invention discloses an electrical coordination control method, equipment and device for a memory and a micro-grid. The method comprises the following steps: presetting a linear control system; setting a set value of a linear predictive controller in the linear control system; the set value comprises a reasonable interval of water temperature in the water heating system; the electric heating effective power generated by the electric heating wire of the electric heating load and the gas heat effective power of the gas-fired boiler are obtained in real time; and generating a control instruction of the gas valve according to the linear control system. When the electric heating load power changes, the linear control system solves the influence mode of the change value of the electric heating load power on the water temperature in the water heating system, and a control mode of a gas valve of the gas boiler for counteracting the influence can be generated; therefore, the gas valve of the gas-fired boiler does not need to be adjusted and coped after the water temperature is changed, large fluctuation of the water temperature in the water heating system can be avoided, and good constant-temperature control over the water temperature in the water heating system is achieved.

Description

technical field [0001] The invention relates to the field of energy interconnection network, in particular to an electrical coordination control method, equipment and device for storage and microgrid. Background technique [0002] Micro-grid (Micro-Grid), also translated as micro-grid, refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. Based on the micro-grid, on the basis of ensuring the stability of the micro-grid, optimize the allocation of resources, and then gradually form the interconnection of the micro-grid, and finally form an energy interconnection network. Energy Internet can be understood as the comprehensive use of power electronics technology, information technology and intelligent management technology to integrate a large number of new power networks, oil networks, natural gas networks and other energy networks compo...
