Heat-storage-type electric heating optimization control method for power failure and heating retention

Abstract

The invention discloses a heat-storage-type electric heating optimization control method for power failure and heating retention. The method comprises the steps that a part of heat in a heat storage water tank is used for meeting the heat load demand during the power failure and does not participate in daily heat supply, and a minimum heating load calculation model during the power failure is acquired; based on the minimum heating load calculation model, a heat-storage-type electric heating optimization dispatching model is established, wherein the model comprises an objective function and a constraint condition; when the power failure occurs, the calculated minimum heating load during the power failure continues to meet the house heat load demand; and from the moment of the power failure,the house heat load demand of a time period set by a user is met, and the indoor comfort level is maintained.

Description

technical field [0001] The invention relates to the field of heat storage electric heating, in particular to an optimal control method for heat storage electric heating without interruption of power failure, which can reduce heating costs while ensuring continuous heating under grid failure. Background technique [0002] Due to its unique heat storage capacity, regenerative electric heating can break the traditional electric heating operation mode of "determining electricity by heat". [1] . On the one hand, users can reduce energy costs by storing heat during off-peak periods; at the same time, they can also optimize heat storage to ensure reliable and continuous heating during power outages. In this field, scholars at home and abroad have carried out a lot of research: Literature [2] uses the RC (Resistor-Capacitance) type of building heat balance to measure the heating load demand, and then optimize the capacity of the heat storage tank; Literature [3] ] constructed an e...

Problems solved by technology

At present, methods commonly used in engineering are to improve the efficiency of power supply emergency repairs and configure emergency power supply vehicles. However, the above methods are all passive responses to power outages and heating. Electricity prices reduce energy costs, limiting the ability of thermal storage electric heating to maintain continuous heating during grid failure periods

Considering that thermal storage electric heating can maintain a certain level of heating based on low-cost and small-capacity backup power when the power grid fails, how to adjust the single pursuit of economy, and store energy through the thermal storage electric heating system The optimization of heat release behavior to improve the reliability of heating needs to be further studied
