Techno-Economic Assessment of PV Power Systems to Power a Drinking Water Treatment Plant for an On-Grid Small Rural Community

This paper shows the technical–economic assessment of two power systems based on renewable electricity to cover energy consumption requirements a drinking water treatment plant in town Pile, Ecuador, with planning horizon 15 years. A stand-alone and grid-connected solar PV system were proposed this plant, which was designed considering maximum daily potable supply condition. operated under scenarios: (1) 12 h during daylight hours (2) 24 h. Both schedules assess impact operation. We modeled optimized total four scenarios, where each scenario consisted one its operating schedules. Homer Pro software used size find an optimal solution scenario, net present cost (NPC) as main criterion for optimization. The results showed that change operation schedule significantly influenced parameters such component sizing, production, initial capital, NPC, purchase/sale capacity from grid service user electric utility company.
