Multi objective queue theory based optimal planning of rapid charging stations and distributed generators in coupled transportation and distribution network Vutla Vijay, Chintham Venkaiah, D. M. Vinod Kumar Energy Storage, 2024 Abstract The environment is adversely affected by greenhouse gas (GHG) emissions from conventional combustion engines. In this regard, electric vehicles (EVs) are a viable transportation option that benefit the environment in reducing GHG emissions. Although the installation of rapid charging stations (RCSs) helps to promote EVs, installing these at improper locations in the distribution network worsens the voltage profile, increases power loss, and energy loss while travelling from EV's current location to RCS. Furthermore, RCS installation cost and waiting time at RCS need to be considered. Therefore, a two‐stage optimal planning is proposed in this article to address the issues stated above. In the first stage, simultaneous optimal planning of RCS and distributed generators is done to minimize active power loss, voltage deviation, EV user cost and to maximize voltage stability index. In the second stage, optimal number of connectors are decided to minimize the installation cost and waiting time in queue at RCS. Here, queuing model is considered to determine the waiting time. A test network of coupled IEEE 33 bus distribution system and transport network is proposed to validate the proposed methodology. Multi objective Rao algorithm (MORA) is used to solve the formulated optimization problems, and results are compared with non dominated sorting genetic algorithm (NSGA‐II) algorithm.

This innovative algorithm outperforms traditional machine learning techniques and metaheuristic methods. By analyzing a wide range of configurations using both labeled and unlabeled data, the optimal setup to minimize electricity costs is identified. In addition, a real-time, rule-based, and efficient home energy management system is presented. The study is based on real data from Australia, including temperature, wind speed, solar radiation, load, and economic and technical information on solar, wind, batteries, and plug-in electric vehicles. The results demonstrate that the proposed model significantly outperforms the conventional Group Method of Data Handling (GMDH), marking a significant advancement in energy planning technology.
Power System Optimization using an Adaptive Fuzzy Campus Placement based Optimization Algorithm A Sunil, Vijay Saieesh, Ch Venkaiah Conference Proceedings 13th IEEE Power and Energy Society Innovative Smart Grid Technologies Asia Isgt Asia 2024, 2024 The use of optimization tools in complex problems is becoming increasingly crucial to overcome the challenging task of achieving efficient results. The Novel Adaptive Fuzzy Campus Placement based Optimization Algorithm (AFCPOA) is a new method for solving optimization problems that is based on campus recruiting process used in universities.

Investigation of Power Flow Analysis in Networked Microgrids Ankeshwarapu Sunil, Chintham Venkaiah International Conference on Smart Systems for Applications in Electrical Sciences Icsses 2023, 2023 In this paper, the power flow analysis of the Networked Microgrids (NMGs) is analyzed for different case studies of benchmark test systems. Multiple Microgrids (MGs) operating in combination enable high penetration of Distributed Energy Resources (DERs), which lowers electricity costs and improves the resilience and stability of the power network. This article's benchmark test system for networked MGs connects and manages four separate MGs. An important technique for operational and planning studies of NMGs is power flow analysis (PFA). Each MG uses tie lines to work alone after initially operating as a group employing all of the MGs. The bus voltages, phase angles, active power loss, reactive power loss, iterations and computational time for NMGs were analyzed.
Multi-Layer Model Classifier for Cyberattack Detection in Smart Electric Grid Sourabh Singh, Ch. Venkaiah 5th International Conference on Energy Power and Environment Towards Flexible Green Energy Technologies Icepe 2023, 2023 In the Smart Grid, communication lines and physical open access points are always prone to cyber-attacks, and electric theft is the most common one. To detect electricity theft, researchers have developed several advanced machine learning models. However, existing work has not explored the problem of data imbalance properly, which is one of the significant challenges in electricity consumption data. This paper aims to compare various data balancing techniques and present an integrated theft detection model. This paper presents a multi-layer model for detecting fraudulent consumers in the smart grid. The detection process starts with data preparation steps, which include data interpolation, outlier handling, and data standardization. The next crucial step is handling data imbalance. Various techniques are tested, and AdaSys performs better than others. The model is being trained on a balanced dataset and validated on a real imbalanced dataset for realistic results. For higher performance, a two-layer model is chosen for electricity theft detection. The first layer consists of three heterogeneous machine learning models, and an Artificial Neural Network (ANN) model is used for the second layer. The first layer's probabilistic prediction serves as input to the second layer, which makes the final prediction. Experimental results confirm that multilayer model classifiers perform better than individual classifiers for detecting cyber-attacks on real consumption datasets.

Optimal Power Dispatch of Multiple DGs Using a Hybrid Algorithm for Mitigating Voltage Deviations and Losses in a Radial Distribution System with Economic Benefits Ankeshwarapu Sunil, Chintham Venkaiah, D. M. Vinod Kumar Distributed Generation and Alternative Energy Journal, 2023 In this research, a meta-heuristic-based hybrid algorithm was used to optimize the power dispatch of numerous Distributed Generators (DGs) in a Radial Distribution System (RDS) for hourly fluctuating seasonal loads in order to reduce losses and voltage variations while also saving money. With hourly seasonal load changes, renewable DGs like PV, Wind, and Hybrid (PV+Wind) were used. The HA is proposed in this paper as a way to achieve successful outcomes by merging two meta-heuristic algorithms. The findings of the HA are compared with Genetic Algorithm (GA), Particle Swarm Optimization (PSO), Shuffled Frog Leap Algorithm (SFLA), and Jaya Algorithm (JA) when they are applied to a standard IEEE 33 bus RDS and PG&E 69 bus RDS. According to the test findings simulated in the MATLAB environment, Hybrid Algorithm (HA) beat GA, PSO, SFLA, and JA in terms of optimal power dispatch of numerous DGs to minimise losses and voltage variations, as well as the cost-benefit analysis of renewable DGs energy generation.
