encounters challenges in its electricity development. In the main grid system, the expansion of load challenge by the issue of power supply quality and reliability The utilization of indigenous renewable energy such as wind and solar power are limited by their intermittency and fluctuation. The development of smartgrid technology provides opportunity to improve the Indonesian electricity BPPT conducts researches on smartgrid applications for both microgrid application in the main grid in Java, and with storage system to increase renewable energy penetration in a small grid. A particular project exploring Wind Power Hybrid Project of BPPT and UNDP attempts wide-spread the technology application for both grid connected and isolated island electrification.

 Indonesia faces rapidly increasing electricity demand. Annual electricity sales growth forecasted at rate of 7%, from 2015 to 2024.  The Government of Indonesia 2025 target is to achieve a national electrification ratio of 95 percent and to increase the renewable energy in the primary energy mix to 23%.  In particular the government has set 2025 targets to increase the country’s total installed wind capacity to 970 MW and national solar capacity to 800 - 1,000 MW.  Two potential areas for renewable energy growth exist in wind energy and rooftop solar PV systems, but still need government regulations to deploy.  Needs for improving the SAIDI and SAIFI 3

 Microgrids are modern, small-scale versions of the centralized electricity system.  Smart microgrids are an ideal way to integrate renewable resources on the community level and allow for customer participation in the electricity enterprise  The transformation from centralized to distributed energy resources brings new challenges for metering, pricing, communication, and distribution.  We strive to optimize the combination of power networks and communication networks (so called smart microgrids) by self-organizing algorithms and mechanisms.  Smart Microgrid applications with PV 500 kWp and battery 500 kWh has been installed in Sumba, East Nusatenggara. 9

• Faster recovery from outage – Smartmeter for automated outage information notification – Distribution automation and advanced switching capability allow sectionalizing and faster distribution circuit reconfiguration to restore healthy sections to service

• Changing landscape of the electric utility grid: – It helps to integrate intermittent sources of generation into the electric power grid – Short term load control for a large number of end-use devices through demand response makes it possible to get quick load relief to match fluctuations in generation. 14
