As more grid-connected photovoltaic (PV) inverters become compliant with evolving interconnections requirements, there is increased interest from utilities in understanding how to best deploy advanced grid-supportfunctions (GSF) in the field. One efficient and cost-effective method to examine such deployment options is to leverage power hardware-in-the-loop (PHIL) testing methods, which combine the fidelity of hardware tests with the flexibility of computer simulation. This paper summarizes a study wherein two Hawaiian Electric feeder models were converted to real-time models using an OPAL-RT real-time digital testing platform, and integrated with models of GSF capable PV inverters based on characterization test data. The integrated model was subsequently used in PHIL testing to evaluate the effects of different fixed power factor and volt-watt control settings on voltage regulation of the selected feeders using physical inverters. Selected results are presented in this paper, and complete results of this study were provided as inputs for field deployment and technical interconnection requirements for grid-connected PV inverters on the Hawaiian Islands.

The combination of Photovoltaic (PV) with a hydrogen storage system as backup (HPVHS - Hybrid PV Hydrogen System) has been proposed in this paper. The Proposed system will cope up with the problems of grid connected PV System (GPVS) which is being stochastic in nature. The control strategy has been proposed for direct and indirect grid voltage regulation utilizing proposed HPVHS as static synchronous compensator (STATCOM). It has been shown that the HPVHS based on this control strategy would improve the dynamic behavior of the GPVS response to disturbance, voltage dips and in a day ahead market where decisions on the power supply should be taken at least 24 hours in advance. MATLAB/SIMULINK based simulation is done and results are provided to show the effectiveness of the proposed control strategy.
