Electric Load Management On Solar Power Plant System

Heightened electricity consumption inversely propotional to the thin fuel supply. Once the sun does not shine optimally during rainy season effecting the output of solar power generation. It been so long on every occasion if solar power unable to supply fully, State Electricity Company (PLN) will take over. This research focuses on designing a device to maximize the usage of solar power when unable to cover full load demand by utilizing Microcontroller Atmega 16. The results obtained to get the voltage according to the standards applicable to load 1 requires a minimum of 600 Watt/m
²
irradiation with a voltage of 217.69 VAC, 2 minimum irradiation loads 800 Watt/m
²
with a voltage of 217.48 VAC, and a minimum load 3 irradiation 1000 Watt/m
²
with a voltage of 217.27 VAC. State Electricity Company (PLN) will supply three loads when the solar panel receives irradiation from 100 - 500 Watt/m
²
. When the solar panel receives irradiation from 600-700 Watt/m
²
, load 1 is supplied by the solar power and load 2 and load 3 are supplied by State Electricity Company (PLN). Meanwhile the solar panel receives irradiation 800-900 Watt/m
²
load 1 and load 2 is supplied by the solar power, and load 3 is supplied by State Electricity Company (PLN). While Irradiation of 1000 Watts/m
²
all three loads are fully supplied by the solar power.
