High efficient operation for a DPGS-HES system using dynamic programming

This paper proposed an operational strategy for a distributed power generation system with hybrid energy storage (DPGS-HES) under dynamic programming (DP). The system, consisting of a generator, batteries and super-capacitors, was primarily designed to satisfy electricity needs in domestic sectors. DP aimed to instantaneously split the power to the multi-source in the DPGS-HES when load demands fluctuated. Simulation results validated its effectiveness where the system had virtuous dynamic performance when the constraints and objectives were met. The overall energy efficiencies were also dramatically improved from 3.84%, 3.67%, 5.15%, 4.14% to 19.69%, 17.47%, 21.48%, 17.75%, respectively in case studies.
