Abstract

The invention discloses an optimized energy dispatching system and method for renewable-energy-source-based combined supply of cooling, heating and power. The system is characterized in that an energy production control module, an energy storage control module and a load control module are respectively connected with an energy management module. The energy production control module, the energy storage control module and the load control module collect field energy supply, energy storage, and load device information respectively and carry out data exchange with the energy management module by a field bus; the energy management module receives and stores the information uploaded by the energy production control module, the energy storage control module and the load control module; and with the information, short-term prediction and/or ultra-short-term prediction of the renewable energy or load can be realized and short-term optimization and/or ultra-short-term optimization of cooling/heating supply, cooling/heating storage, power supply, power storage and operating states of the dispatching function unit can be realized.

Description

technical field [0001] The invention belongs to the field of combined cooling, heating and power, and relates to a combined cooling, heating and power system based on renewable energy, in particular to an energy optimization scheduling system and method for combined cooling, heating and power of renewable energy. Background technique [0002] Energy shortage and environmental pollution have become major social problems to be solved urgently. It is predicted that my country's energy gap will be about 2.5×10 in 2030 8 tons of standard coal, will reach 4.6×10 in 2050 8 tons of standard coal. On the other hand, my country's current thermal power-based energy supply method has low energy utilization efficiency and serious waste. What's more serious is that a large amount of harmful substances produced during the combustion of fossil fuels have made the air quality worsen day by day, and extreme weather such as smog occurs frequently. It is estimated that 80% of PM2.5 pollution...
