Investigation of power output from PV arrays under different fault conditions is an essential task to enhance performance of a photovoltaic system under all operating conditions. Significant reduction in power output can occur during various PV faults such as module disconnection, bypass diode failure, bridge fault, and short circuit fault under non-uniform shading conditions. These PV faults may cause several peaks in the characteristics curve of PV arrays, which can lead to failure of the MPPT control strategy. In fact, impact of a fault can differ depending on the type of PV array, and it can make the control of …

While renewable power generation and vehicle electrification are promising solutions to reduce greenhouse gas emissions, it faces great challenges to effectively integrate them in a power grid. The weather-dependent power generation of renewable energy sources, such as Photovoltaic (PV) arrays, could introduce significant intermittency to a power grid. Meanwhile, uncontrolled PEV charging may cause load surge in a power grid. This paper studies the optimization of PEV charging/discharging scheduling to reduce customer cost and improve grid performance. Optimization algorithms are developed for three cases: 1) minimize cost, 2) minimize power deviation from a pre-defined power profile, and 3) combine objective …

Typical Photovoltaic System For A Commercial Building, Florida Solar Energy Center, Gobind Atmaram
FSEC Energy Research Center®
This paper covers the design and installation of an 11 peak kilowatt (kWp) grid-connected photovoltaic system on the roof of the new facilities at the Florida Solar Energy Center (FSEC7). The main objectives of this work are to demonstrate the application of photovoltaics (PV) as a demand-side management option for meeting peak commercial electric loads and provide a typical PV array and system design for commercial buildings. The PV array consists of 48 ASE America=s EFG ribbon silicon modules and is interfaced with three Omnion 4kW power conditioners. The complete array and system electrical design and installation were performed by …
Fsec Procedure For Testing Stand-Alone Photovoltaic Systems, Florida Solar Energy Center
Fsec Procedure For Testing Stand-Alone Photovoltaic Systems, Florida Solar Energy Center
FSEC Energy Research Center®
This procedure is based on IEEE P1526/D1, Draft Recommended Practice for Testing the Performance of Stand-Alone Photovoltaic Systems. The system performance is based upon how well it can charge the battery. The usable battery capacity is measured by charging and discharging the battery three separate times. The tests are designed to test the overall system performance in the span of about one month.

Florida Power Corporation (FPC) owns and operates a 15-peak-kilowatt (kWp) amorphous silicon photovoltaic (PV) system at its Econ substation in Orlando, Florida. The PV system, commissioned on August 23, 1988, was designed to generate power that would be injected directly to the FPC electric grid. The Solar Progress Generating Station was developed as part of FPC's interest in new power generation technologies. The PV system design and installation was a collaborative effort among FPC, the Florida Solar Energy Center (FSEC), Sandia National Laboratories (SNL), and the Electric Power Research Institute (EPRI).In March 1999, FPC informed FSEC that the PV system …

The decision to install a PV array on a rooftop should be followed by the questions where, what, and how. Site selection determines where the array will be installed. The system design provides details on what hardware will be used; and the selected mounting method determines how the array will be attached to the roof.

A recent resurgence of interest in roof-mounted photovoltaic systems has prompted the Florida Solar Energy Center to assess the current state of the technology from a systems viewpoint. A major part of the system that is often underestimated in the performance and economics of the system is the roof structure. The type of roof can significantly affect both the initial cost of an installation and the life cycle costs.

On June 3, 1998, researchers from the Florida Solar Energy Center (FSEC) conducted a field test of six, independent photovoltaic (PV) systems at the Florida Power and Light (FPL) Martin Power Plant. The weather conditions during test were hazy with a few clouds. This test was performed at the request of FPL to determine the operational status of the PV systems and to provide recommendations for upgrading or repairing these systems. Of the six systems, three were fully operational and were providing power to the grid.
