The performance of a utility interactive photovoltaic (PV) system relies on several key components within the system. The effects of long term operation on utility interactive inverter performance are the topic of this paper. Years of anecdotal evidence indicates that the PV module typically has a 1% per year degradation in performance; this is accepted by industry for how modules are typically rated...
Because of their deployment in dispersed locations on the lowest voltage portions of the grid, photovoltaic (PV) systems pose unique challenges to power system engineers. Computer models that accurately simulate the relevant behavior of PV systems would thus be of high value. However, most of today's models either do not accurately model the dynamics of the maximum power point trackers (MPPTs) or...
As photovoltaic systems proliferate on grids, larger numbers of inverters will be interconnected with each other through their host utility. This becomes especially true if string inverters (SIs) or AC module ldquomicroinvertersrdquo are used. It will thus become increasingly important to ensure that the islanding detection methods used are effective in this so-called ldquomulti-inverter caserdquo...
