Analisa Dampak Masuknya Photovoltaic (PV) Dalam Skala Besar Terhadap Performa Sistem Tenaga Listrik

Abstract

Abstract Photovoltaic (PV) is a renewable energy generator that produces electrical energy at a certain
time or also called intermittent.. A large number of PV penetrations into the system significantly affects the
ability of conventional generators to catch up with power due to decreased PV output power or when PV
output power is not available. This is due to the different characteristics of the lean rate of each type of
generator. To overcome the power imbalance in the electric power system with various compositions, it is
necessary to limit the number of PV that is allowed to be installed in the electrical power interconnection
system.
In this study, the generator and load data were used collectively from the Indonesian National Great
Company. The power plants used are hydropower plant, steam power plant, geothermal power plant, diesel
power plant, gas engine power plant, and gas power plant. Based on the simulation results, the number of PV
that is allowed to be installed is a maximum of 30 percent of the total generation in a certain generation
configuration. If the amount of PV exceeds the maximum limit, there will be a power imbalance between the
generator and the load. If the generator configuration has a large generator capacity and has a high lean rate,
PV plants can be connected to the electrical power interconnection of more than 30 percent of the total generation.
