Study and Design of Off-Grid PV Power System in Pirien, Asmat Regency, Papua Province using MATLAB/SIMULINK

Electricity is a basic need for humans. Areas that have been electrified can improve the economy and prosperity in the area. Indonesia's Electrification Ratio in 2018 has reached 98.05% and for Papua has the smallest electrification ratio of 81.66%. The problems faced in increasing electrification are infrastructure and distribution of power plants, especially in remote areas. Indonesia has the potential in solar resources. One solution that can be done is to build a power plant using an off-grid electricity system. Besides this, the off-grid electricity system is also influenced by geographical conditions, potential resources, and the burden that will be supplied so that technical and economic analysis needs to be done. In this paper we will discuss technical and economic analysis of the off grid system. For technical analysis used MATLAB software and economic analysis using HOMER Pro. Each case will be implemented in Pirien, Asmat Regency, Papua as a sample. Based on the results obtained, the technical analysis using MATLAB can be more comprehensive because the input data can be arranged based on the desired time. This paper also describes the Maximum Power Point Tracking algorithm, that is Perstrub and Observation Algorithm and the design of components such as DC-DC Converters, Inverters, and Batteries used in off-grid power systems.
