Abstract

The invention relates to a control method and device for combined supply system of cooling, heating and power, a computer and a storage medium. The method includes: converting a jacobian matrix into adiagonal polygon matrix equation, solving the diagonal polygon matrix equation to obtain a correction value of each variable in the combined supply system of cooling, heating and power, calculating energy flows of a cooling network, a heating network and a power supply network in the combined supply system of cooling, heating and power according to the correction values, and performing output power control on the system. By implementing the embodiment of the invention, the energy flow of the combined supply system of cooling, heating and power can be quickly and accurately calculated, and theoutput power of the combined cooling heating and power system can be controlled.

Description

technical field [0001] The present invention relates to the technical field of electric power system, in particular to a control method, device, computer and medium of a combined cooling, heating and power supply system. Background technique [0002] The combined cooling, heating and power system is a total energy system based on the concept of energy cascade utilization and integrates refrigeration, heating and power generation. A typical combined cooling, heating and power system usually consists of three parts: power generation equipment, refrigeration system and heating system. In order to calculate the energy flow of the combined cooling, heating and power system, the related technologies usually adopt the following two methods: (1) the unified iterative method, which combines the energy flow equations of the cooling network, heating network and power supply network for unified solution, It is necessary to form the unified iteration Jacobian matrix of the entire integr...
