Optimal Design Capacitive Energy Storage (CES) for Load Frequency Control in Micro Hydro Power Plant Using Flower Pollination Algorithm

The use of micro hydro power generation is increasingly chosen, because it has advantages economically, technically, and environmentally friendly. Operation of micro hydro requires appropriate control technology. Micro hydro is very suitable for use in areas that are difficult to reach the central power grid. A common problem with micro-hydro systems is the unstable turbine spin, caused by changes in loads from consumers. This causes a change in the frequency fluctuations in the system that can cause damage from the factory side and from the side of the consumer electrical appliances. Therefore, in this research we will discuss the strategy of load frequency control based on Capacitive Energy Storage (CES). CES is a tool that can store energy quickly and release energy in a certain time. In its use required proper adjustment for CES parameters. To obtain optimum CES parameter on micro hydro artificial intelligence method based on Flower Pollination Algorithm (FPA). The simulation results show that FPA application to test CES parameter add Proportional Integral Derivative (PID) controller to micro-hydro, can accelerate response time of change of frequency change and also increase overshoot frequency response system, that is equal to -2.325e 06 to 5,197 e-07 pu.
