Control and operation of a microgrid can be operated at grid connected or islanded modes. In this paper, the microgrid consists of a Diesel, PV modules with a distributed energy storage system, loads, and inverter. The purpose of power management is to control the stability of the system to cope with changes in load and interconnection with other networks. The stability of the microgrid is also obtained by setting the load connected to the system. Power management is also controls the operation of each plant based on the condition of the energy sources used as a source of generation. In islanded mode, the main goal of power management is to stabilize the system, in terms of frequency and voltage. In grid connected mode, typical objectives are to minimize the price of energy import at the point of common coupling (PCC).

The electricity export-import scheme using rooftop solar PV by PLN customers, commonly known as net metering or net billing, was not attractive because it was only valued at 0, 65:1 for each price of electricity sold to the price of electricity in general. In mid-2021, the Ministry of Energy and Mineral Resources will revise the provisions on the export of electricity by valuing 1:1 for each electricity price sold. However, changing the export-import scheme can eliminate compensation for the cost of storing consumer electricity which PLN will bear in the future. At this time, the emergence of more proactive consumers with production and storage capabilities in the context of renewable energy, in other words, "prosumers", can bring new opportunities or challenges for the operation of energy systems in the electricity market environment. Recently, the Peer-to-Peer Energy (P2P) system has been one of the new recommendations for the design and operation of the electricity market. This mechanism allows customers to trade their electricity directly to their neighbours through a P2P service provider platform. The absence of research related to the elaboration of business models that can encourage the implementation of P2P and, in the future, the benefits of P2P itself to be channelled properly encourages this research to analyze the business model that will be offered from the side of P2P service providers in the form of startup companies. In this study, nine elements of the Business Model Canvas (BMC) are used as guidelines for implementing P2P platform service providers based on Rooftop Solar PVs for residential areas in Indonesia. Offered. From the consumer side, this research describes the Value Proposition Canvas (VPC), which can help consumers know when consumers will get what they want and what difficulties they will face with a P2P platform in the future. In addition, from the service provider's perspective, the application of BMC can help to produce a good business model translation which must have a balance between several requirements which are divided into three terms, namely feasibility (technical), desirability (customer) and Viability (economics) of the product.

Tunda Island is one of the islands in a group of 17 islands in the north of Java, Banten Province. Electrical energy in Tunda Island is supplied by 2 Private Diesel Genset, each of which has an installed capacity of 100 kVA and 75 kVA, with an operating time of 4-5 hours per day starting from 18.00 to 22.00. The microgrid electrical system has several advantages, in terms of efficiency, microgrid can reduce the use of fossil fuels in power plants, besides that it can reduce losses caused by the distribution system because the location of the microgrid generator is relatively close to the load. In terms of reliability, the microgrid electrical system can optimally manage energy sources for 7 days and 24 hours. In addition, the microgrid electrical system has the ability to work without being connected to the grid. With the use of a microgrid electricity system, the electricity costs that must be paid are less and most importantly can reduce carbon emissions, because the plants used in the microgrid electricity system generally use renewable energy. In this study, scenarios were made to determine the most optimum LCoE value using an optimization approach with the help of homer pro software. The operating pattern for the Tunda Island electricity system is obtained, namely, the load is carried during the day by Solar PV Power Plant and at night using a generator that has been controlled using the force on & force off mode. From the simulation obtained the lowest LCoE in the Solar PV Power Plant Hybrid configuration with capacity of 240 KWp, 302.4 KWh battery & 200 KW inverter. The ability to pay for electricity for the residents of Tunda Island is still possible if subsidized tariffs are imposed, the range of ability to pay for the residents of Tunda Island is IDR/KWh 726.45-1452.91 and their ability will decrease if they are subject to non-subsidized PLN tariffs. With PLN as the PSO, the differrence in tariffs with the local Generation Production Cost will receive a subsidy from the government. Furthermore, the sustainability of this microgrid system will have the benefit of a continuous supply of electricity. So, it can be felt by the people of Tunda Island which is managed by State-Owned Enterprise (PT. PLN Persero).
