Distributed voltage control for distribution feeder with photovoltaic systems

2018 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2018
The voltage fluctuations in an active distribution system is a challenging problem which requires an effective solution to empower the expansion of photovoltaics (PV). In this study, distributed voltage control which leverages the smart inverter technology, is proposed as a solution.

Visualizing the Surface Photocurrent Distribution in Perovskite Photovoltaics

Small, 2022
AbstractDefect states play an important role in the photovoltaic performance of metal halide perovskites. Particularly, the passivation of surface defects has made great contributions to high‐performance perovskite photovoltaics. This highlights the importance of understanding the surface defects from a fundamental level by developing more accurate and

Integration of Photovoltaic Distributed Generation in the Power Distribution Grid

2012 45th Hawaii International Conference on System Sciences, 2012
Numerous North American utilities are integrating growing numbers of investor-owned photovoltaic distributed generation (PV-DG) plants into their distribution systems to comply with state-mandated Renewable Portfolio Standards (RPS). Given the fact that distribution systems have been designed to be operated in a radial fashion, interconnection of PV-DG

A distributed control for multiple photovoltaic generators in distribution networks

Proceedings of the 2011 American Control Conference, 2011
A distributed control was provided to regulate the active power of photovoltaic (PV) generators installed on a distribution power system network, making a group of PVs converge and operate at the same ratio of available power. The sufficient conditions that guarantee the convergence of the closed-loop system was discussed, including the minimal ...

Analysis of interconnection of photovoltaic distributed generation

2011 IEEE Industry Applications Society Annual Meeting, 2011
Rapid growth of grid-connected photovoltaic distributed generation (PV-DG) provides many benefits such as clean energy, reduced emissions and creation of new green jobs. However, given its intermittent nature, large scale penetration of PV-DG may challenge the quality and reliability of the grid. This paper evaluates the impact of PV-DG on distribution

Assessing the Value of Distributed Photovoltaic for the Distribution System

3rd Renewable Power Generation Conference (RPG 2014), 2014
This work discusses performance indices associated with distributed photovoltaic generation. It is suggested that expressing the indices as monetary values can simplify interaction of distribution engineers with consumers that install their own generation.

Adaptive distributed MPPT algorithm for photovoltaic systems

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
Fast change of the irradiance conditions entails failure of the maximum power point tracking (MPPT) algorithm in a photovoltaic system (PVS). In this paper it is proposed the combination of a modified Perturb and Observe (P&O) distributed MPPT and an adaptive algorithm.

Maximizing the Benefits of Distributed Photovoltaics

The Electricity Journal, 2012
Distributed photovoltaics can present benefits and costs to electric power systems. These effects can be challenging to quantify, though thoughtful applications of distributed PV can maximize benefits and minimize costs. Several regulatory changes can encourage such applications.
