Power Management and Simulation of Renewable DC Power System

摘要

This paper presents a method to manage the Independent renewable power source DC system, such as a stand alone solar/fuel cell system, to achieve the maximum using efficiency of the system. The system includes the power generation, energy storage, power bus and Power electronics parts. Scenarios, modes, loads and power sources decide the different control status and load priority. The MATLAB simulation shows not only the achievement of maximum energy efficiency but also a high level performance of the power system.
