Economic Dispatch Pada Pembangkit Listrik Tenaga Diesel Gas (PLTDG) Menggunakan Fuzzy Logic Controller (FLC)

In every fulfillment of electricity needs, a power plant unit is operated using various fuels. But the biggest expenditure from the operation of the plant is on the cost of using the generator unit fuel which is around 60%, so a solution is needed to minimize the cost of generating fuel in operating the generating unit. Economic Dispatch is a way to overcome the economic operating problem of a power plant by dividing the load on each operating unit in order to obtain minimum generation costs. The problem of Economic Dispatch can be done using the Fuzzy Logic Controller (FLC) method because the FLC method can make very complex decisions and in its application does not require mathematical models that are too difficult to solve, so that the FLC method is expected to minimize the cost of generating electricity. The results of calculating the Economic Dispatch using the FLC method result in a lower total production cost compared to the total total production cost of the System and the Lamda Iteration method for 24 hours on September 30, 2017.
