Operation of Charge Controllers in Distributed Multi Source (Solar and Wind) Hybrid Power Generating Systems

In large PV hybrid power systems, battery management is critical due to the continuous operation of the power system, the limited power available for temperature control in the battery room, and the high cost of maintenance.Charge controllers are required in solar or wind power generating systems where electrical energy storage is required in these systems. Optimal charging is required in order to improve the performance and life of the batteries. The charge controllers are used for optimal charging of the entire system. The different types of charge controllers, terminologies, set points and importance of hybrid system are explained in this paper. The shunt and series type charge controller’s current and voltage regulations are shown and battery current and voltage characteristics according to the source availability and load applied are also shown for the understanding.The studies of a system of the three sources (Solar, wind and diesel generator) includes than it in practice to optimize performance by 35% by optimal charging of battery using charge controller
