To meet the power demand, the wind generator operates to generate power. When the power demand can be met with the wind energy generation, energy storage system is not supplying power to the load . If the demand is more than the wind power generator, energy storage system is operated along with windmill.
In this paper, standalone operation of wind energy power generation and storage is discussed. The storage is implemented using supercapacitor, battery, dump load and synchronous condenser. The system is simulated for different power generation and storage capacity. The system is regulated to provide required voltage.
When the power demand can be met with the wind energy generation, energy storage system is not supplying power to the load . If the demand is more than the wind power generator, energy storage system is operated along with windmill. The demand can be met exactly with the operation of both windmill operation and battery storage system .
The basic block diagram of the windmill power generation system with energy storage system is shown in Fig. 1. The block diagram shows that the windmill is used to convert the wind power to electrical power, and it is rectified using rectifier to convert ac into dc signal.
The main components of storage system for variable speed windmill power generating systems are step down transformer, PMSG, battery, supercapacitor, peripheral interface controller, DC/DC converter, synchronous condenser, dump load. In this system, step down transformer is connected to convert 230 V AC supply from mains to 5 V DC.
The battery storage system in the wind power generation system can provide an improved efficiency with less consumption of the fuel. When the windmill generation is more than the required demand, it can be stored in the battery for future use .
