On-line control strategy for instantaneous power management of hybrid power system based on dynamic fuzzy logic controller

This paper presents the basis for the development of an intelligent and autonomous energy management strategy for Hybrid Power System(HPS). This strategy is designed by applying on-line Takagi-Sugeno fuzzy logic principles. As a result the fuzzy control system gets rid of the limits of the HPS, which has the imprecision, uncertainty, strong coupling and nonlinearity, to achieve its tractability, robustness and low solution cost. Under the operation constraints related to each type of sources, the simulation results show that the load demand are satisfied for all time, the energy storage system is managed in an optimal way and the fuel use is optimal.
