Photovoltaic (PV) energy plays an important role in the energy transition, especially for off-grid contexts, through a format of Hybrid Energy System (HES) with storage system. Yet, using a storage system comes with additional investment costs, extra environmental impact and maintenance issues, etc. For an off-grid PV/Diesel HES, a precisely designed Power Management System (PMS) with short-term solar forecast could be used to reduce or even avoid the use of energy storage system. Hence, this work aims to find out the feasibility of this concept, and introduce a new approach to evaluate the HES performance rather than using classic statistical metrics like Root Mean Square Error (RMSE) and MAE (Mean Absolute Error). Besides, several scenarios are tested to explore the influence of different elements on HES performance.
