| Summary: | The study and implementation of renewable energy as a source of electricity
generation are developing both nationally and globally. This is because of
awareness in using electricity source which are environmental friendly and
renewable. In addition, renewable power plants can also provide economic
benefits. The intermittent nature that has been the main issue of renewable plants
also can be overcome, one of which by hybrid energy storage. One power plant type
which is a combination of both is photovoltaic – battery storage hybrid power plant
(PV-Battery Hybrid) which consist of photovoltaic power plant and battery storage
system.
A renewable power plant project that is going to be carried out in Indonesia is PVBattery
Plant connected to a coal mining and processing power system in Bontang.
The existing system itself is a stand-alone micro grid system which is not connected
to larger grid such as PLN’s. Comparison between the photovoltaic capacity and
existing system is quite large, where the photovoltaic capacity is 3 MWp, about
18% of 16.5 MW system existing peak load. Therefore a comprehensive feasibility
study is required to ensure that the PV-Battery Plant will be well integrated with
the existing system.
The objective of this study is to analyze the feasibility of connecting the PV-Battery
Hybrid to the Bontang Coal Mine Power System. Some included analyzes are power
flow analysis, transient stability analysis, short circuit analysis, and coordination
of protection analysis. The existing system and the PV-Battery Hybrid are modeled
in a software to be simulated and analyzed based on some case test and determined
criteria of feasibility. From the result it is concluded that interconnection of the PVBattery
Hybrid to the existing system is technically feasible, with some notes of
recommendations on the existing system setting. It is also expected that the detailed
methodology presented in this study can be a reference for feasibility study of
renewable power plant interconnection, especially regarding the connection of
photovoltaic – battery storage power plant to microgrid.
