“…In the literature, this problem is solved using pseudo-measurements. Due to the intermittent and unpredictable behavior of consumptions and distributed energy sources, the generation excess could lead to a reversed power flow, from the consumers to the supply external point [18,19]. This drawback requires a real-time effective voltage control strategy [20], particularly under islanded operation modes, to obtain the best solutions, with reliable effects on the minimization of energy losses, and energy efficiency improvement [21,22].…”

The majority of the existing electricity distribution systems are one-way networks, without self-healing, monitoring and diagnostic capabilities, which are essential to meet demand growth and the new security challenges facing us today. Given the significant growth and penetration of renewable sources and other forms of distributed generation, these networks became "active," with an increased pressure to cope with new system stability (voltage, transient and dynamic), power quality and network-operational challenges. For a better supervising and control of these active distribution networks, the emergence of Smart Metering (SM) systems can be considered a quiet revolution that is already underway in many countries around the world. With the aid of SM systems, distribution network operators can get accurate online information regarding electricity consumption and generation from renewable sources, which allows them to take the required technical measures to operate with higher energy efficiency and to establish a better investments plan. In this chapter, a special attention is given to the management of databases built with the help of information provided by Smart Meters from consumers and producers and used to optimize the operation of active distribution networks.

The quality of power is a major concern for the utilities and the power industries. Since the 1980’s, the term power quality has become a very prevalent one. There are various factors that affect the power quality, such as sag, swell, and power factor variation. The main cause of these issues is the use of non-linear loads. In a RES based grid-connected system, harmonics variation is one of the main issues that can affect the quality of power. Hence to address this in this paper Unified Power Flow Controller (UPFC) is proposed for the grid connected system. Many papers were proposed with the various FACTS devices but the performance of the proposed system exhibits a better one. In this paper application of UPFC is implemented in MATLAB/Simulink on test cases of wind-based grid connected system and PV based grid connected system. The performance of the proposed UPFC is compared with conventional Voltage Source Inverter (VSI). In all the cases the proposed UPFC exhibits the improved performance. This ensures the reduction in the harmonics in the power system in future.

“…RE generation's more significant contribution to the displacement of its fossil fuel-driven counterparts however comes in the form of large-scale grid integration, bringing with it added challenges to existing electrical grids. Li et al (2017) investigate this, noting the most significant challenges are increased system voltage levels, increased short-circuit currents, deterioration in power supply reliability and power quality, highlighting the importance of a strong stable grid for successful large-scale RE integration. A major contributing factor is noted to be RE's lacking contribution to system inertia, which refers to the loss of conventional generation's spinning reserves.…”

Purpose Despite South Africa’s ailing electrical grid, substantial renewable energy (RE) integration is planned for the country. As grid-integrated RE affects all grids differently, this study aims to develop an adaptable grid code-guided renewable power plant (RPP) control real-time simulation testbed, tailored to South African grid code requirements to study grid-integrated RE’s behaviour concerning South Africa’s unique conditions. Design/methodology/approach The testbed is designed using MATLAB’s Simulink and live script environments, to create an adaptable model where grid, RPP and RPP guiding grid codes are tailorable. This model is integrated with OPAL-RT’s RT-LAB and brought to real-time simulation using OPAL-RT’s OP4510 simulator. Voltage, frequency and short-circuit event case studies are performed through which the testbed’s abilities and performance are assessed. Findings Case study results show the following. The testbed accurately represents grid code voltage and frequency requirements. RPP point of connection (POC) conditions are consistently recognized and tracked, according to which the testbed then operates simulated RPPs, validating its design. Short-circuit event simulations show the simulated wind farm supports POC conditions relative to short-circuit intensity by curtailing active power in favour of reactive power, in line with local grid code requirements. Originality/value To the best of the authors’ knowledge, this is the first design of an adaptable grid code-guided RPP control testbed, tailored to South African grid code requirements in line with which RPP behavioural and grid integration studies can be performed.
