“…The results show that the voltage stability is improved significantly, but on the other side, it will decrease the efficiency of the power system because in case the inverter absorbs reactive power, the grid in turn provides the amount of reactive power needed by PVPP. Some researchers used extra hardware for reactive power control such as STATCOM 92 and FACTS 93 devices, but these devises not only increase the system cost but also increase the system complexity and affects the stability.…”

Summary The high integration of photovoltaic power plants (PVPPs) has started to affect the operation, stability, and security of utility grids. Thus, many countries have established new requirements for grid integration of solar photovoltaics to address the issues in stability and security of the power grid. In this paper, a comprehensive study of the recent international grid codes requirement concerning the penetration of PVPPs into electrical grids is provided. Firstly, the paper discusses the trends of PVPPs worldwide and the significance of improving grid codes' requirements. In addition, the comparison of common requirements covered in the majority of international grid codes considers high‐ and low‐voltage ride‐through capabilities, voltage and frequency regulation, and active and reactive power support requirements. Finally, a broad discussion on the compliance technology challenges and global harmonization of international grid codes that the PVPPs have to address is presented. The study summarizes the most recent international regulation regarding photovoltaic integration and research findings on the compliance of these regulations and proposed recommendations for future research. It also can assist power system operators to compare their existing requirements with other universal operators or establish their own regulations for the first time. Additionally, this research assists photovoltaic manufacturers and developers to get more accurate understanding from the recent global requirements enforced by the modern grid codes.

In this paper, new Adaptive Neuro-Fuzzy Inference System (ANFIS) and PI controller have been proposed and investigated which the power system is equipped by Static Var Compensator (SVC) and small wind turbine. The SVC is controlled by PI controller optimized by genetic algorithm (GA) to regulate the voltage profile. To demonstrate the efficiency of proposed controller, a Single Machine Infinite Bus (SMIB) has been considered, in which small fluctuation of mechanical damped has been applied to improve the transient stability and has been evaluated using a relative rotor criteria. Obtained results have demonstrated a better performance with ANFIS and PI controller in which both voltage and transient stability have been controlled perfectly.

“…Figure 1, adopted from [9,12], illustrates the basic structure of an UPFC which consists of two frequency converters: a parallel transformer (denoted as TRP) with a frequency converter 1 and a serial transformer (denoted as TRS) with a frequency converter 2. The converter 1 and 2 are operated from a common DC link provided by a DC storage capacitor: parallel CP and serial CS condenser battery.…”
