| Summary: | The drive towards achieving Net Zero Emission goals in the future necessitates an
energy transition. Power plants based on fossil fuels must be replaced with those
based on new and renewable energy sources. In Indonesia, Renewable Energy
Power Plants (REPPs) such as Solar Power Plants (SPPs) and Wind Power Plants
(WPPs) are highly favored. These plants are susceptible to weather intermittency,
causing power fluctuations. These fluctuations affect the system frequency
deviation, which must operate within normal conditions according to the Grid
Code. Implementing an Automatic Dispatch Control System (ADCS) can control
power generation to address frequency issues. With ADCS, the system can operate
automatically and be controlled to adjust to real-time conditions, such as power
fluctuations due to intermittent generation. In this study, the application of ADCS
for dispatch control of diesel generators and Battery Energy Storage Systems
(BESS) will be examined. ADCS control will be conducted for response times of one
and three minutes. Fluctuation data from SPPs and WPPs will be recorded for 30
seconds. Without ADCS control, the system's frequency deviation operates outside
the normal operating range due to power mismatches between scheduled and actual
power due to fluctuations from SPPs and WPPs. With ADCS control, power
fluctuations can be compensated for by diesel generators and BESS. Dispatch
analysis will use Discrete Fourier Transform (DFT) analysis to divide the power
mismatch signal into high and low-frequency components. The high-frequency
power mismatch signal will be used for BESS dispatch, while the low-frequency
signal will be used for diesel generator dispatch. The research results show that the
ADCS response for a one-minute response time is better than for three minutes. |
