Developing a tourist resort with no power grid on the island. We need a solution that can provide 24-hour electricity for the entire resort, including guest rooms, restaurants, seawater desalination plants, sewage treatment plants, and air conditioning systems. Establish an isolated microgrid based on diesel generator sets. Multiple generator sets are usually installed to provide basic power through a parallel system.In order to reduce the high cost of diesel transportation and minimize noise pollution, an increasing number of projects are combining solar photovoltaic systems to form hybrid energy systems. The generator mainly operates during periods of no sunlight or peak load.
