[IEEE 2018 7th International Conference on Renewable Energy Research and Applications (ICRERA) - Paris, France (2018.10.14-2018.10.17)] 2018 7th International Conference on Renewable Energy Research and Applications (ICRERA) - Power Flow Control of a Standalone Photovoltaic-Fuel Cell-Battery Hybrid System

摘要： The major challenge facing photovoltaic (PV) sources penetration, especially for standalone applications, is their intermittent nature; hence hybrid systems arise where more than one energy source feed the same DC-bus. In this paper, a hybrid PV-fuel cell system is considered to serve a variable DC load under environmental changes. PV is considered the primary source of energy whereas the fuel cell (FC) is its backup. To enhance system reliability and cost effectiveness, batteries are added to supply energy during emergencies. A load sharing strategy is presented and tested for a variable load and irregular irradiation profile. Simulation results validated the proposed strategy, fulfilling a daily residential load during summer and winter months in Egypt.
