Abstract: Photovoltaic (PV) panels have attracted a lot of research interest in the past decade due to their clean and renewable character as an energy source. However, their intrinsic low conversion efficiency has been a major drawback, imposing the need for a huge initial cost of investment. Additionally, due to the low efficiency, PV system installations also require large surface area for panel installation. External factors such as temperature and soiling and shading further reduce the performance of the PV panels operation under real world conditions. Furthermore, the processes used in the fabrication of PV panels do not allow the improvement of panel efficiency once the fabrication is completed. Thus special techniques are required for the modulation of performance on the field. Thermal management schemes and cleaning techniques have been developed to alleviate this existential challenge. Additionally, PV panels operation in the field has been boosted via the improvement of the solar collection methods such as solar trackers, solar concentrators and panel tilt angle. This paper presents a critical comprehensive review of the different PV panel technologies and their field operation challenges as well as the strategies used to enhance the performance of silicon photovoltaic modules (the most attractive single junction PV panels in the market) under field conditions.

Abstract: Renewable Distributed Generation (RDG) is a promising alternative to conventional power generation methods because it reduces power losses and dependence on central power generation. However, when DG is deployed, it doesn’t always provide the reactive power needed for proper voltage regulation leading to low voltage on some buses. To achieve the maximum benefits of a DG unit, a combined DG and D-STATCOM allocation is evaluated. The selection of the optimal capacity and position of these compensators requires appropriate optimization methods to be solved. The real and reactive power loss reduction and voltage profile improvement was selected as objective function and the Artificial Bee Colony (ABC) optimization algorithm was used to solve the optimal allocation problem under variable load conditions. Four case studies, including combined DG / D-STATCOM at the same location (Case III) and combined DG / D-STATCOM at separate locations (case IV), were considered under different load factors of normal, light and peak loading conditions. The performance analysis of these approaches was tested on the standard IEEE 33-bus radial distribution system. The MATLAB 2021b environment was used for the simulations. The outcomes showed that applying optimal DG and D-STACOM at separate locations resulted in a better percentage real power loss reduction of (76.34%, 75.95%, and 75.41%) compared to combined DG/D-STATCOM at the same location, which recorded (72.41%, 71.62% and 71.12%) under normal, light and peak loading conditions. Similarly, optimal DG/DSTATCOM at separate locations recorded better reactive power loss reduction (72.71%, 72.71%, and 72.11%) compared to DG/D-STATCOM at the same location, which recorded (66.57%, 66.57%, and 65.98%) under the said loading conditions. However, DG/D-STATCOM at the same location offered slightly better voltage profile improvement.
