There has been remarkable increase in the amount of decentralized wind farms (WFs) in sub-transmission grids. The high penetration of WFs causes complicated impacts on power flows and voltages. Therefore, WFs have to operate bus voltages of the sub-transmission grid continuously within a permissible range. Furthermore, WFs should transfer required amount of reactive power into transmission grid and/or...
Wind energy is clean, affordable, efficient and effectively infinite. Therefore, it is the biggest player in energy transition arena and penetration of it in power systems is increasing. The high penetration of wind farms (WFs) causes problems because wind itself is variable and uncertain. Moreover, it results in complicated effects on power flows and voltages. Grid operators are supposed to develop...
This paper provides an assessment on voltage profiles of a distribution system in the presence of high level of solar rooftop PV penetration. Each household solar rooftop PV power generation is calculated by PVWATTs online calculation tool. Load profile of South-West Chiang Mai City of the Provincial Electricity Authority (PEA) of Thailand is selected for the simulation. Simulation results indicate...
