| Summary: | As a component of the energy internet, micro-energy grid can realize the step utilization of energy by combining the cooling, heating and power technology and the new energy power generation technology. The load-side cooling, heating and electric loads of the micro-energy grid in the park have a large demand response potential. This paper aimed at the lowest comprehensive operation cost of the park, and constructed an optimal scheduling model considering the demand response of the micro-energy grid under grid-connected operation. The model included the demand response model of shiftable load and transferable load. And the delay and inertia of the heat load were taken into account in the demand response. Then an improved interval optimization algorithm fused with particle swarm optimization was proposed to optimally solve the objective function. The simulation examples verified that the model proposed in this paper can reduce the load peak-valley difference and realize economic operation under grid-connected condition, on the other hand, it can realize high energy utilization and low pollutant emissions. |
