Singapore situates in the equatorial region and solar resources are the most viable renewable energy option it has. Therefore, Singapore targeted to boost up its solar capacity roughly 7 times from today’s capacity by 2030, it is equal to an increase from 260 megawatt-peak (MWp) of installed solar capacity to 2 gigawatt-peak (GWp). (Tan, 2019) However, solar energy is greatly affected by surrounding environment conditions. Such as intermittency of sunshine, urban shading and temperature changes. These conditions will cause fluctuation and noise to the output power of a solar generation system. This project aims to develop a multiloop controller for a transformer-less grid connected solar photovoltaic (PV) generation system. Simulation on software and testing on hardware will be conducted to achieve different control objectives.
