Optimal Sizing of Hybrid Energy Storage in Industrial Park Integrated Energy System

The multi-vector energy solutions such as combined heat and power (CHP) units and heat pumps (HPs) can fulfil the energy utilization requirements of modern industrial parks. The energy storage systems play important role in both electricity and heating networks to accommodate increased penetration of renewable energies, to smooth the fluctuations and to provide flexible and cost-benefit coordination between electric and thermal systems. However, the cost and associate life span of the storage systems have become the main obstacles at current stage. Consequently, an energy storage collaborative allocation method is proposed for industrial park integrated energy system utilizing bi-level optimization model. The techno-economic value has been evaluated through simulation.
