Electricity being a basic national infrastructure for a country, its security, reliability and quality are the most important parameters for the network managers. Several methods are generally used to improve the voltage quality more and more. However, most of the means implemented depend on external factors independent of the network managers or require huge regular financial resources. The method used in this paper is the loopback, applied to the Southern Interconnected Grid (SIG) of Cameroon, which is the largest network in the country. The procedure used takes into account nodes experiencing huge voltage drops and network constraints. The chosen loopback scenario results in a clear improvement of the voltage plan in this network, and also a discharge of the transformers, a considerable decongestion of the lines, a reduction of the power losses and a significant reduction of the thermal placement used for improvement of the voltage profile.

The low‐voltage (LV) distribution network is the last stage of the power network, which is connected directly to the end‐user customers and supplies many dispersed small‐scale loads. To achieve environmental targets and to address the energy shortage issue, governments worldwide increase the renewable energy sources (RESs) into the electricity grid. In addition, different types of low carbon technologies (LCTs) such as electric vehicles are becoming widely used. A significant portion of RES and LCTs is penetrated into the LV distribution network, which poses a wide range of challenges. To address these challenges, there is a persistent need to develop traditional planning and operation frameworks to cope with these new technologies. In this context, this study provides a comprehensive review of planning, operation, and management of LV distribution networks. The characteristics, types, and topologies of LV distribution networks plus different aspects of operation and planning are investigated. An insightful investigation of the reasons impacts and mitigation of voltage and current unbalanced in LV networks is provided. Moreover, the main three‐phase power flow techniques used to analyse the LV networks are analysed.

“…As PV penetration levels increase, one of the important issues is to realize potential impacts of PV integration on distribution networks such as voltage profile, power losses, stability, and reliability 5,6,10 . Voltages at the customer service entrance are kept by utilities within an allowable limit (±5) during 24 hour of the day in order to guarantee satisfactory system operation and lifetime of customer equipment.…”

Summary The rising demand for electrical energy and decreasing capital cost of photovoltaic (PV) panels led to rapid growth in large‐scale solar PV system penetration in many countries, including Turkey. This article focused on a cost‐effective and efficient decentralized voltage and reactive power (Volt/Var) control approach in distribution networks at the presence of high penetrated solar PV farms utilized as static synchronous compensator (PV‐STATCOM) which has been recently proposed. A proper coordinated control of large number of PV‐STATCOMs suggested to achieve optimal reactive power scheduling for the next day ahead. This article introduced implementation of a modified Lévy flight‐based firefly algorithm (MLFA) to multi‐objective Volt/Var optimization problem, which was employed for minimizing active power loss and cost of energy. The validity and applicability of the proposed method were confirmed by implementing it on a real megavolt (MV) Turkish distribution network for various loading conditions. Simulation results show that the results of MLFA to this problem outperform those of other methods. Furthermore, application of the proposed method offers opportunity to distribution system operators for a large amount of cost savings and loss reduction without compromising voltage regulatory limits.
