Resumo

Renewable energy sources such as wind and photovoltaic (PV) have great potential for reducing fuel consumption in diesel-based mini-grids in remote communities. However, the fluctuating and intermittent nature of these sources can give rise to a number of problems in mini-grids with high penetration of non-dispatchable renewables with reduced or non-existent storage units. This paper proposes the use of a frequency x power droop control strategy for curtailing the output power of PV inverters during periods of excess of power in a diesel-dominated mini-grid. This approach reduces the operation of the diesel genset under part (light) load conditions, reducing frequency variation, and avoids overvoltages in the mini-grid. The theoretical analysis is verified by means of digital simulations with PSCAD.
