The Day-ahead Optimization Scheduling of CCHP Energy System with Multi-mode Energy Storages

The continuous development of society and economy has accelerated the energy crisis and environmental pollution. As a typical representative of energy ladder utilization, CCHP energy system can cooperate with energy storage facilities to play a comprehensive role in energy utilization. This paper first establishes a CCHP energy system model with P2G-based Storage System (P2GSS) and heat storage (HS). Then, with the goal of system operation cost and energy consumption minimum, a CCHP pre-optimization scheduling model considering the uncertainty of renewable energy was established. Finally, an example was used to compare the effects of different energy storage modes on the system. The results prove that the reasonable setting of energy storage can effectively reduce the system cost. P2GSS is conducive to the rational use of resources by the CCHP system and reducing energy waste.
