Abstract

The invention provides a method and device for calculating the virtual energy storage capacity of a heat / cold supply system and electronic equipment; the method comprises the steps: building a heat flow model of the system according to the structure of the heat / cold supply system; according to the real-time measurement information of the heat / cold supply system, determining the real-time operation state information, and solving a heat flow model of the heat / cold supply system; according to the solving result of the heat flow model, determining the running states that the virtual energy storage amount of the heat / cold supply system is zero and the virtual energy storage amount is full, and calculating the instantaneous energy storage power limit and the instantaneous energy discharge power limit; under any preset adjustment duration, based on the real-time operation state information of the heating / cooling system, solving and optimizing a heat flow model of the heating / cooling system according to the upper limit constraint condition and the lower limit constraint condition of the heat transfer fluid temperature in the pipe network and the indoor temperature of the user side; and obtaining the average energy storage power limit, the average energy release power limit, the energy storage capacity and the energy release capacity of the heat / cold supply system under the adjustment duration according to the optimization result.

Description

technical field [0001] The invention relates to the technical field of energy utilization, in particular to a calculation method, device and electronic equipment for virtual energy storage capacity of a heating / cooling system. Background technique [0002] Making full use of renewable energy is an effective way to achieve sustainable energy development. However, renewable energy such as wind and light has the characteristics of intermittency and volatility, and its large-scale and high-proportion consumption requires effective use of the adjustment capabilities of other equipment, components or links in the energy system to fully enhance the overall flexibility of the energy system . [0003] In order to evaluate the energy storage characteristics of equipment, components, links, etc. with adjustment capabilities in the energy system, the concept of "virtual energy storage" has been proposed. The flexibility of the energy system can be improved by adjusting the energy stor...
