The impacts of grid-tied photovoltaic on some power quality indices are introduced. Relevant standards of power quality indices are presented. Assessment techniques of the impacts are comprehensively reviewed. The state of the art uncertainty modelling of PV systems are reviewed. Stochastic and deterministic methods of assessment are compared.
The assessment methods of the impact of rooftop PVs on the distribution network have been the focus of the research community in recent years. The main challenge is to create a computational framework to deal with the uncertainty from PV system.
High penetration of photovoltaic (PV) generation in low voltage (LV) distribution networks can leads some power quality problems. One of the most important issues in this regard is the impermissible voltage deviation in periods with a large imbalance between PV generation and local load consumption. Accordingly, many authors deal with this issue.
This section studies the assessment techniques of the impact of rooftop PVs on power quality analysis. The focus is on three power quality issues: voltage unbalance, voltage rise and harmonic distortion. The effort is on reviewing the most recent techniques to model the uncertainty and perform the stochastic assessment. 3.1. Voltage unbalance
Many countries have experienced a surge in the level of the penetration of solar PV systems in the last decade. A huge portion of the newly deployed PV systems are connected to low voltage Grid.
