Multi-Energy Complementation Comprehensive Energy Optimal Dispatch System Based on Demand Response

The comprehensive energy system is constantly developing. How to meet the society and the environment as the premise and construct an optimal dispatch strategy is the main research direction of the current energy system development. In the study, multi-energy complementarity is considered, based on demand response, and a Multi-energy Complementation (MEC) optimal dispatch model is established based on Conditional value at risk (CVaR), and finally the energy system optimal dispatch test simulation evaluation under different circumstances is carried out. The simulation results show that the MEC comprehensive energy optimal dispatching system proposed in the study takes the demand side response into account, and the WP energy utilization of the system is more reasonable. When the demand side response is fully considered, the highest load value is 574.12 kW. After considering the demand side response and carbon emission, the average daily carbon emission of the system is only 59.36 kg. When the demand side response and carbon footprint are not considered, the carbon footprint of the gas-fired boiler in the system is always maintained at 32.31 kg, and the carbon emission is small. The comparison of the energy optimal dispatching system shows that the system cost proposed by the research is only 8880.93 yuan; the carbon emission cost is only 417.83 yuan, significantly lower than other systems. The above results show that, after considering the demand side response, the MEC comprehensive energy in the park can be more effectively optimized and the load distribution of the system can be improved, which is of great significance in power grid dispatching.
