“…In addition, with the requirement of significant land area for the deployment comes a higher set up cost with lower capacity factor compared to other renewable technologies. The authors of [60] presented an extensive review of the topologies for the large-scale PV plants taking into consideration the internal topology and the AC collection grid. The authors of [61] illustrated an thorough analysis of control strategies of grid-connected inverters with their applications in PV plants.…”

Decarbonisation, energy security and expanding energy access are the main driving forces behind the worldwide increasing attention in renewable energy. This paper focuses on the solar photovoltaic (PV) technology because, currently, it has the most attention in the energy sector due to the sharp drop in the solar PV system cost, which was one of the main barriers of PV large-scale deployment. Firstly, this paper extensively reviews the technical challenges, potential technical solutions and the research carried out in integrating high shares of small-scale PV systems into the distribution network of the grid in order to give a clearer picture of the impact since most of the PV systems installations were at small scales and connected into the distribution network. The paper reviews the localised technical challenges, grid stability challenges and technical solutions on integrating large-scale PV systems into the transmission network of the grid. In addition, the current practices for managing the variability of large-scale PV systems by the grid operators are discussed. Finally, this paper concludes by summarising the critical technical aspects facing the integration of the PV system depending on their size into the grid, in which it provides a strong point of reference and a useful framework for the researchers planning to exploit this field further on.

“…The PV generator consists of a PV array interconnected with a single PV inverter and a transformer ( Figure 1) in which the different components are 65 connected in central configuration [5]. To develop the mathematical model of the PV generator, the analysis is divided into two parts: (i) PV array model and (ii) the PV inverter together with the transformer model.…”

The present article assesses the study of the PV generator capability curves for use in large scale photovoltaic power plants (LS-PVPPs). For this purpose, the article focuses on three main aspects: (i) the modelling of the main components of the PV generator, (ii) the operational limits analysis of the PV array together with the inverter, and (iii) the capability curve analysis considering variable solar irradiance and temperature. To validate this study a PVPP of 1MW is designed, modelled and simulated in DIgSILENT PowerFactory .The results for each case scenario shows that the capability curve and the limitations are directly affected by: the solar irradiance, temperature, dc voltage, and the modulation index.

Summary Voltage fluctuation and voltage rise are common issues associated with the massive integration of photovoltaic (PV) technologies in distribution systems. In this paper, sensitivity‐based and optimization‐based methods are proposed for mitigating voltage fluctuation and rise in the presence of plug‐in hybrid electric vehicles (PHEVs). The concept of these methods is to optimize the reactive power of PV inverter and active power from charging station of PHEVs for matching a target voltage profile. The sensitivity‐based method is based on the first‐order power flow sensitivities around the desired voltage profile. An optimization model is used in optimization‐based to minimize the mismatches between the fluctuating and required voltage profiles. The charging/discharging operation of PHEVs and reactive power of PV inverter are simultaneously controlled for compensating power fluctuation during cloud transients and load fluctuations. The results demonstrate the effectiveness of the proposed methods compared with existing methods.
