Capacity Allocation Optimization of Components in Regional Integrated Micro-energy System

Through realizing the mutual supply of power, gas, heating, cooling and other energy systems, regional integrated micro-energy system (RIMS) could make full use of the absorption capacity of renewable energy, and improve the comprehensive utilization rate of energy. The capacity allocation of components is the key content of RIMS design. This paper establishes an optimization model with the objective of minimizing the cost of unit productivity and constraints of energy balance, equipment outputs and charging & discharging power of energy storage devices. A case of RIMS was studied to verify the model. Simulation results show that the proposed capacity allocation optimization model could effectively reduce the cost of unit productivity, reduce peak-valley difference of various types of loads and improve utilization efficiency of clean energy.
