A 3 kV, 18 kW medium-voltage PV plant demonstrator

Abstract : Today, photovoltaic (PV) plants operate at low DC voltage (maximum 1.5 kV) and inject power in the low-voltage, single-phase or three-phase public grid via an inverter. In PV plant from some hundreds of kilowatt, power is injected in the medium-voltage three-phase public grid using transformer between the inverter and the grid. PV plants of hundreds of megawatts are today in operations and siliconcarbide (SiC) power semiconductors with high breaking voltage capabilities are available on the market or under samples, allowing to design static converter with higher efficiency than IGBT based ones. This leads to consider the development of DC-side medium-voltage PV plant for high power applications. An 18 kW, 3 kV PV string is built to demonstrate the feasibility of such a medium-voltage PV plant.
