Impact of photovoltaic systems integration on electricity distribution networks

Traditionally, power systems are designed to operate in a unidirectional power flow. In the past few years, integration of solar photovoltaic (PV) systems on distribution network has grown rapidly given its potential technical and economic benefits, which include higher network utilization, enhanced...

Electronics Nuclear engineering Traditionally, power systems are designed to operate in a unidirectional power flow. In the past few years, integration of solar photovoltaic (PV) systems on distribution network has grown rapidly given its potential technical and economic benefits, which include higher network utilization, enhanced reliability and loss reduction. However, the high PV generation during low demand periods may cause potential network problems. In addition, PV generation depends directly to the sun irradiance which could potentially cause problems in the cases of high PV penetration level. The intermittency of the power generated from the PV plants may introduce voltage fluctuation and power quality issues. These issues may limit the PV penetration level and hence necessary measures are needed to alleviate the potential problems. This dissertation investigates the steady state impact of the PV plant penetration on the operation of power distribution networks. This includes the impact of PV generation of the network losses.

The results indicate that the integration can have a positive impact and negative impact on the connected grids. The interest lies in the voltage improvement at load buses and the reduction in the system losses. The maximum capacity and the impact of the PV on the grid connected system depend on the PV size, installation location and system topology.
