Load frequency control (LFC) of micro-hydro power plant with Capacitive Energy Storage (CES) using Bat Algorithm (BA)

Utilization of Microhydro Power Plant (MHPP) is more widely used in remote areas because it has advantages in economic, technical, and good nature. But the problem that often occurs is the rotation from the generator not constant because change of load by consumer. The burden of change causes a change of frequency where it can cause damage to the system and consumer equipment. To support optimum performance of MHPP, is needed a technology to design appropriate controls. This study will be discussed a strategy based on frequency control Capacitive Energy Storage (CES) and PID. For optimal performance, the needed tuning appropriate for CES-PID parameter. To obtain the CES-PID parameters optimized in MHPP used artificial intelligence method namely Bat Algorithm (BA). The simulation shows that the application of BA-CES-PID can increase settling time and correct the overshoot of the system frequency respons.
