Power Flow Management and Control of Hybrid Wind / PV/ Fuel Cell and Battery Power System using Intelligent Control

This paper deals with the power flow modulation and control using the various power system. In this paper the efficient usage of power produced is defined. The battery management system is introduced in order to store the excess power produced and use that power in case of power deficiency. The battery management is controlled using the fuzzy logic controller which is one of the intelligent controllers. The fuzzy logic controller is responsible for the battery charging and discharging according to the dc load requirement. There are three power systems wind, PV and fuel cell connected to the bus bar. The total power system supplies to the load of approximately 10KW. The dc load connected to the power system is variable so the power which supplied to the load is not constant. If the power produced is greater than that of load the fuzzy logic controller closes the breaker 1 contacts and opens the breaker 2 contacts so the battery gets charged. If the power produced is not up to the load requirement then the breaker 2 contacts closes and breaker 1 opens the battery gets discharged. By this method the power supply is constantly given and the wastage of power is reduced and the constant working of load is achieved. The whole setup is done using the MATlab/ SIMULINK software.
