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

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 ...

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

Impact of Photovoltaic Distributed Generation on Generation Resource Allocation

2013 46th Hawaii International Conference on System Sciences, 2013
Various aspects of electricity generation resource allocation and planning are presented in this study on a hypothetical example of the generation resource pool of the state of Georgia augmented by a substantial amount of photovoltaic renewable generation, likely to happen in the next several years due to increased proliferation of PV, supported by ...

Impact of increased distributed photovoltaic generation on radial distribution networks

2016 International Conference on Control, Decision and Information Technologies (CoDIT), 2016
In this paper, the analysis is carried out over distribution test systems. The analyses show that voltage variation problems occur in different nodes of the distribution networks with an increase of penetration level. However, proper selection of dispersion level can improve the voltage profile and decrease losses of the distribution systems. Depending

Event Management Layer for Distributed Generation Photovoltaic Inverters

2020 IEEE International Conference on Industrial Technology (ICIT), 2020
This paper proposes a multi layer management approach for power inverter control of grid connected photovoltaic systems. Initially, an event management model is derived from the photovoltaic inverter unit, in which the set of uncontrollable events is accounted for as perturbed terms added to the controllable nominal set model.

Transformer for Distributed Photovoltaic (DPV) Generation

2018 International Conference on Electrical, Electronics, Communication, Computer, and Optimization Techniques (ICEECCOT), 2018
The demand for Distributed Photovoltaic (DPV) generation is increasing due to its benefits of supplying Electric Power without carbon emission, lower cost and associated benefits. The DPV generation requires inverter fed transformers for grid connection.

The impact of distributed photovoltaic generation on residential distribution systems

2012 North American Power Symposium (NAPS), 2012
The past few decades have seen a rapid proliferation of distributed generation sources. These sources can be located at or near load centers and provide benefits which traditional generation may lack. However, distribution systems were not designed to accommodate such power generation sources as they might cause bidirectional power flow and other ...

A comparative study of MPPT methods for distributed photovoltaic generation

2012 IEEE PES Innovative Smart Grid Technologies (ISGT), 2012
Photovoltaic (PV) energy generation is becoming an increasingly prevalent means of producing clean, renewable power. PV is renewable, reliable, and domestically secure. One of the most important components of PV systems is the inverter technology that converts the direct current (DC) power output from the PV panel or array to alternating current (AC ...

Distributed Online VAR Control for Unbalanced Distribution Networks With Photovoltaic Generation

IEEE Transactions on Smart Grid, 2020
The unbalanced nature of the distribution networks (DNs) and communication asynchrony pose considerable challenges to the distributed voltage regulation. In this paper, two distributed voltage control algorithms are proposed to overcome these challenges in multiphase unbalanced DNs.
