Abstract
Diesel Generator set was found to be a favorite power generator in a remote area. In this area, diesel genset usually consumes a significant amount of diesel fuel with higher fuel price than an urban area. Diesel Generator capacity conventionally prepared twice bigger or more than the existing load to prevent any load spike from designated equipment. This work implements an Energy Management System to cut the spike with the support from battery storage unit and photovoltaic module. Once the Energy Management System cut the load spike using battery/photovoltaics, Diesel Generator loads no longer need to be irrelevantly bigger than the existing load. The current experiment in the remote island at Raja Ampat archipelago indicates that the using of 80 kVA Diesel Generator can be reduced to 42 kVA Diesel Generator. This Diesel Generator replacement induces fuel consumption up to 50 %. With this designed work, a smart microgrid with PV-Battery-Diesel can be installed in a designated remote area with lower fuel consumption.
Highlights
Microgrid installment in a remote area such as a small island or an isolated village in the middle of the jungle is a very significant aspect for the local people to get electricity
There are some previous researches on increasing Diesel genset (DG) performance by connecting the additional equipment or integrating the renewable energy (RE) source to assist DG unit
The integration was using an energy management system (EMS) unit consisted of a smart inverted unit which could cut off any occurring load spike and facilitated energy supply from solar farm to the DG’s microgrid
Summary
Microgrid installment in a remote area such as a small island or an isolated village in the middle of the jungle is a very significant aspect for the local people to get electricity. As the lower layer of smart grid [1], the microgrid is self-supplied electricity distributed system consisting a power generation system, having its own storage system, isolated load and limited coverage area. There are some previous researches on increasing DG performance by connecting the additional equipment or integrating the renewable energy (RE) source to assist DG unit. As the potential of RE combination, wind power, and solar energy is the most available renewable sources in the remote area rather than rarely find hydro power or expensive tidal/wave power generation system
