Abstract
Optimal reactive power dispatch has a purpose to achieve secure and economic operation of power system by regulating reactive power allocation in electric power system, such as regulating generators voltage, capacity of shunt capacitors and tap position of transformers. The optimal reactive power dispatch is complex combinatorial optimization problem and more easily solved by using artificial intelligence-based methods. This paper presents the solving of optimal reactive power dispatch problem to minimize active power loss using grey-wolf optimizer method with Lampung electrical power system as a case study. Matpower 5.1 software is used to calculate power flow and active power losses. The simulation is performed by regulating the voltage on each bus or substation connected to the generator with the limit of 0.95 pu to 1.05 pu, adjusting tap position of transformer on Gumawang and Seputih Banyak substations with a limit of 0.95 pu to 1,025 pu and regulating the capacity of shunt capacitors in Natar, Sutami and Kalianda substations with a limit of 0 to 25 MVAR. The simulation results show that the gre-wolf optimizer method can reduce the total active power losses from 18.97 MW to 18.2377MW.
