Optimal energy management for a connected microgrid using dynamic programming method

This paper presents optimal energy management using dynamic programming for a grid-connected including PV system and battery energy storage system (BESS). The main goal is to minimize the system's cash flow and the power exchange with the main grid and also to maintain the balance between generation and consumption as well as optimal operating conditions. Another method of management based on rules, the ruled-based technique, has been proposed which guarantees the respect of the imposed constraints, but which has limits that will be exposed. A simulation has been carried out to verify and evaluate the efficiency of the proposed methods.
