1. Introduction

   The increasing global demand for electricity has led to a significant expansion of power transmission networks, with transmission lines playing a crucial role in delivering electricity from power plants to consumers. However, the transmission of electrical power over long distances results in substantial power losses due to the resistance of transmission lines. These power losses not only lead to significant energy wastage but also result in increased greenhouse gas emissions, reduced transmission grid efficiency, and higher electricity costs. To address this challenge, dynamic voltage control has emerged as a promising strategy for minimizing power losses in transmission lines. By leveraging advanced smart grid technologies, dynamic voltage control enables the real-time adjustment of transmission voltage, optimizing power flow and reducing energy losses. This approach has significant implications for improving transmission grid efficiency, reducing the environmental impact of power transmission, and enhancing the overall reliability of the power system. Dynamic voltage control can be optimized using advanced algorithms and machine learning techniques, considering factors such as transmission line parameters, load demand, and generator output.

   The implementation of dynamic voltage control in transmission systems can lead to significant energy savings, reduced power losses, and improved transmission grid performance. Furthermore, dynamic voltage control can also help to mitigate the impact of renewable energy sources on transmission grid stability, by adjusting transmission voltage in response to changes in renewable energy output. Additionally, dynamic voltage control can be integrated with other smart grid technologies, such as energy storage systems and demand response programs, to create a more efficient, resilient, and sustainable power grid. Overall, dynamic voltage control has the potential to play a critical role in the development of a more efficient, reliable, and environmentally friendly power transmission system.

   The development of dynamic voltage control systems requires careful consideration of a range of technical, economic, and environmental factors. From a technical perspective, dynamic voltage control systems must be able to respond quickly and accurately to changes in transmission line parameters, load demand, and generator output. This requires the use of advanced sensors, communication systems, and data analytics. From an economic perspective, dynamic voltage control systems must be able to provide a sufficient return on investment, through reduced energy losses, improved transmission grid efficiency, and increased reliability. From an environmental perspective, dynamic voltage control systems must be able to reduce greenhouse gas emissions, through reduced energy losses and improved transmission grid efficiency. Overall, the development of dynamic voltage control systems requires a careful balancing of technical, economic, and environmental factors, in order to create a more efficient, reliable, and environmentally friendly power transmission system.

   The integration of dynamic voltage control with other smart grid technologies has the potential to create a highly efficient and resilient power transmission system. For example, the combination of dynamic voltage control with energy storage systems can help to mitigate the impact of renewable energy sources on

2. LITERATURE SURVEY

   A.Dynamic reactive power compensating based on fuzzy logic in power transmission grids

   The existing methods for dynamic reactive power compensation in power transmission grids include Static Var Compensator (SVC), Static Synchronous Compensator (STATCOM), Thyristor-Controlled Series Compensator (TCSC), Thyristor-Controlled Shunt Reactor (TCSR), Switched Capacitor Banks, and Synchronous Condenser. These methods use various control strategies such as Proportional-Integral (PI) Control, Proportional-Integral- Derivative (PID) Control, and Feedback Linearization Control to regulate the reactive power output of the compensator. Additionally, optimization techniques such as Linear Programming (LP), Non-Linear Programming (NLP), and Genetic Algorithm (GA) are used to optimize the reactive power output of the compensator. These methods have been widely used in power transmission grids to improve voltage stability, reduce power losses, and increase grid flexibility. However, these methods have limitations, such as complexity, computational requirements, and sensitivity to input variables. For example, SVCs and STATCOMs require complex control systems and have high installation costs. TCSCs and TCSRs have limitations in terms of their compensation range and require precise tuning of their control parameters. Switched Capacitor Banks have limitations in terms of their switching speed and require complex control systems. Synchronous Condensers have limitations in terms of their compensation range and require complex control systems. Therefore, there is a need for more advanced and sophisticated methods, such as fuzzy logic-based methods, to improve the performance and efficiency of dynamic reactive power compensation systems. Fuzzy logic-based methods can provide more accurate and robust control of reactive power output, and can handle comlex and non-linear systems more effectively.

These software tools allow for the modeling and simulation of complex transmission line configurations and can provide detailed information on energy losses and electromagnetic fields. Furthermore, some researchers have also used artificial neural networks (ANNs) and machine learning algorithms to predict energy losses in overhead transmission lines based on various input parameters such as transmission line arrangement, conductor size, and terrain characteristics.

   C.Minimizing Power Losses in Distribution Networks: A Comprehensive Review

   Minimizing power losses in distribution networks is crucial for efficient electrical distribution power flow. Several existing methods can help achieve this goal. Reconfiguration techniques, which involve changing the open/closed status of some sectionalizing and tie switches, can reduce real power losses and improve voltage profiles. Installing capacitor banks and implementing power factor correction can also reduce power losses. Optimization techniques, such as linear programming and genetic algorithms, can be used to optimize the distribution network and minimize power losses. Incorporating distributed generation can help reduce power losses by generating power closer to the load. Optimizing the switching of distribution lines and properly selecting the conductor size and transformer size can also help reduce power losses. Additionally, other methods such as using advanced materials and technologies, like high- temperature superconductors and nanomaterials, can also be used to minimize power losses in distribution networks. These methods can be used individually or in combination to minimize power losses in distribution networks, and their effectiveness can be evaluated using various performance metrics, such as loss reduction, voltage improvement, and cost savings.

   D.Transmission line loss and load allocation via Artificial Bee Colony algorithm

   The existing methods for transmission line loss and load allocation include traditional optimization techniques such as Linear Programming (LP), Quadratic Programming (QP), and Dynamic Programming (DP), which are used to minimize transmission line loss and optimize load allocation. Other methods include evolutionary algorithms such as Genetic Algorithm (GA), Particle Swarm Optimization (PSO), and Ant Colony Optimization (ACO), which are used to search for optimal solutions. Additionally, methods like Newton-Raphson method, Gauss-Seidel method, and Fast Decoupled Load Flow method are also used to solve the load flow problem and optimize transmission line loss and load allocation. Furthermore, other swarm intelligence algorithms like Bacteria Foraging Algorithm (BFA), Artificial Immune System (AIS), and Harmony Search Algorithm (HSA) are also used to solve the transmission line loss and load allocation problem. These existing methods have their own advantages and disadvantages, and the Artificial Bee Colony (ABC) algorithm is proposed as a new approach to solve this problem.
