Load Dispatching of Energy Hub Based on Robust Optimization in Energy Internet Environment
Presently,the extensive grid connection of intermittent renewable energy generation(REG)affects the reliability and flexibility of power system.By transmitting the surplus power generated by REG to power to gas(PtG)and power to heat(PtH)equipment,the flexibility and the consumption level of REG can be effectively improved.This paper presents a load dis-patching model of residential energy hub(EH)based on energy conversion technology.The proposed EH includes PtG,PtH,combined heat and power(CHP)units and heat storage equipment.In order to deal with the fluctuation and uncertainty of elec-tricity price,the robust optimization model is taken to control the robustness level of the model.The simulation results show that the model is effective in minimizing operation cost and reliable operation.
