“…In [13], a review of existing grid integrated PV-based topologies was presented. Readers should refer to [8,9] for more comprehensive explanations for various PV structures and their technologies. In the category of distributed systems, PV may be broadly classified into four types: (1) very large scale; (2) large-scale; (3) medium Scale, and (4) small scale PV systems.…”

“…A PV-based power generation unit usually works in the grid connected mode. Nevertheless, unlike conventional generation units, high-capacity PV units, like in the range of multi MW, will have a huge effect on the dynamic performance of the interconnected power system and also will have an important impact on the reliable and stable operation of interconnected systems [9,10]. Thus, in the view of the assessment of the grid-connected operation characteristics of the grid scale PV systems, researchers have carried out a vast number of modeling and control studies on dynamic impact and PV system and their contribution on grid support and ancillary services [11,12].…”

This paper reports a general overview of current research on analysis and control of the power grid with grid scale PV-based power generations as well as of various consequences of grid scale integration of PV generation units into the power systems. Moreover, the history of PV renewable growth, deregulation of power system and issues related to grid-connected PV systems considering its contribution to various responsibilities like frequency control, virtual inertia capabilities and voltage regulation are discussed. Moreover, various outcomes of the high-penetrated grid with PV power plants such as power quality, active and reactive power control, protection, balancing and reliability under various loading conditions are reviewed and discussed.

“…Dedicated standards for the interconnection of LS-PVPPs to the grid are the ones presented in Germany (BDEW), US (FERC LGIA) and Puerto Rico (PREPA). According to these standards, not only inverter's disconnections 155 is forbidden, but they also have to provide grid support functions as voltage and frequency regulation as well as fault ride through capability [52], [53]. To help to comply these requirements FACTS and capacitor banks are included, but they are not part of these review.…”

The concern of increasing renewable energy penetration into the grid together with the reduction of prices of photovoltaic solar panels during the last decade have enabled the development of large scale solar power plants connected to the medium and high voltage grid. Photovoltaic generation components, the internal layout and the ac collection grid are being investigated for ensuring the best design, operation and control of these power plants. This article addresses the review of components as photovoltaic panels, converters and transformers utilized in large scale photovoltaic power plants. In addition, the distribution of these components along this type of power plant and the collection grid topologies are also presented and discussed.

“…Therefore, traditional voltage regulators may not be sufficient to control the rapid voltage variations caused by fluctuations of renewable energy generation [3], especially in remote networks [4]. In this situation, reactive power compensation through PV inverters is first proposed to improve the voltage profile due to their availability and low cost [5][6][7][8]. However, with low X/R ratio of rural distribution systems, reactive power compensation methods for voltage regulation are not as effective as those in transmission systems.…”

Abstract-There are more large-scale PV plants being established in rural areas due to availability of low priced land. However, distribution grids in such areas traditionally have feeders with low X/R ratios, which makes the independent reactive power compensation method less effective on voltage regulation. Consequently, upstream Step Voltage Regulator (SVR) may suffer from excessive tap operations with PV induced fast voltage fluctuations. Although a battery energy storage system (BESS) can successfully smooth PV generation, frequent charge/discharge will substantially affect its cost effectiveness. In this paper, a real-time method is designed to coordinate PV inverters and BESS for voltage regulation. To keep up with fast fluctuations of PV power, this method will be executed in each 5s control cycle. In addition, charging/discharging power of BESS is adaptively retuned by an active adjustment method in order to avoid BESS premature energy exhaustion in a long run. Finally, through a voltage margin control scheme, the upstream SVR and downstream PV inverters and BESS are coordinated for voltage regulation without any communication. This research is validated via an RTDS-MatLab co-simulation platform, and it will provide valuable insights and applicable strategies to both utilities and PV owners for large-scale PV farm integration into rural networks.Index Terms--Coordinated voltage control, photovoltaic (PV), battery energy storage system (BESS), real-time control, state of charge (SOC) regulation.
