Renewable energy systems throughout theworld has a major weakness that they are highly dependent on the renewable resources that are intermittent in nature and in some cases are difficult to be predicted. Standalone PV system solves part of this problem by combining with battery bank. This paper focuses on the design, modeling, simulation, and performance evaluation of standalone PV system with DC distribution system for rural area electrification in Ethiopia. The model is systematically explained and the components are presented in great details. For the production of energy for a remote load, PV is the primary power sources of the system and battery is used as a backup for long run application. A remote village Wadila-Guaza with 25 homes was taken, and the needs for rural homes were identified and loads were selected. Data like load demand, solar energy resource, and weather conditions of the area was collected from primary and secondary resources, to test the performance of the system. MATLAB is used to model a PV Source, battery bank, DC-DC converter, and control system of each component. Design and modeling of each component in the proposed system are described. For the performance evaluation, emphasis is on voltage stability and system reliability under different operating conditions. Results from the simulation demonstrate the feasibility of the proposed system and DC distribution for the rural area to support the houses during non-generation periods and distribution network voltage stability under different operating conditions.
