Outdoor Monitoring – India SEC Dhiraj Magare

Aim: Modeling the effects of environmental parameters on photovoltaic (PV) module performance To analyze the PV module performance one can study the effect of seasonal variation on three different PV technologies (i.e. a-Si (amorphous silicon), HIT (Hetero-junction with Intrinsic Thin layer) and mc-Si (multi crystalline silicon)) installed at National Institute of Solar Energy (NISE), Gurgaon […]

Distribution Voltage Control Considering the Impact of PV Generation on Tap Changers and Autonomous Regulators

The uptake of variable Mega Watts from Photovoltaic(PV) challenges distribution system  operation. The primary problem is significant voltage rise in the feeder that forces existing voltage control devices such as on-load tap changers (OLTCs) and line voltage regulators (VRs) to operate continuously. The consequence is the deterioration their operating life. Also, conventional non-coordinated reactive power […]

Generation of Synthetic Benchmark Electrical Load Profiles Using Publicly Available Load and Weather Data

Authors: G. Pillai, G. Putrus, N. Pearsall Elsevier International Journal of Electrical Power and Energy Systems, October 2014 Electrical load profiles of a particular region are usually required in order to study the performance of renewable energy technologies and the impact of different operational strategies on the power grid. Load profiles are generally constructed based on […]

Near-Term Economic Benefits from Grid-Connected Residential PV Systems

Authors: G. Pillai, G. Putrus, T. Georgitsioti, N. Pearsall Elsevier Energy, April 2014 One of the main reasons attributed to the slow uptake of grid-connected residential PV (photovoltaic) systems, is the lack of information about the near-term economic benefits which are as important as long-term viability for residential customers. This paper presents a comparative assessment of […]
