Interconnection of hydro power plant through 20 kV distributed line to improve electrical power supply in Dieng Central Java

Hydro power plant is possible to be present and has interconnection to distribution line. The presence of such power plant is expected to supply additional power and overcome voltage drop at load side. In this paper, several experimental works based on simulation and primary data from field measurement are presented to show the performance of interconnection of hydro power plant through 20 kV distribution line to improve electrical power supply in Dieng - Central Java. Several requirements were observe and investigated by conducting simulation experiment. Several analyses such as Load flow, short circuit and stability were performed. As the results, the presence of hydro power plant has given positive impact to the profile of voltage in 20 kV distribution system. All power flows to the load properly and no reverse power back to the power plant or substation.
