  • The use of SVM and AR Methods for allotment of Load Scheduling and Energy Management in SPS
    Sulakshana Bhausaheb Mane, S. Thangalakshmi, R. Umamageswari, C Praveenkumar, Asala Riyadh Sarhan, and Omar Muhsin
    IEEE
    Integration of photovoltaic (PV) systems into energy grids to meet the solar energy consumption requires high-performance predictive algorithms Although genetic process (GP) based additive regression (AR) models so provide answers to nonlinear prediction problems For the information Another hybrid model is proposed that combines the SR with a support vector machine (SVM) architecture. The hybrid model seeks to improve accuracy and robustness by using real-world climate data including solar radiation and historical PV power estimates. Using the Elastic Net and Extreme Boosting methods, the hybrid AR-SVM algorithm makes fast feature selection by eliminating redundant inputs. Stability and reliability are ensured by maintaining the hyper-criteria during the training and testing phases. The model reduces the computational complexity and improves accuracy by using fewer layers and neurons. The improved prediction accuracy is demonstrated by simulation results, which show a significant reduction in the absolute error (MAE) and root mean squared error (RMSE) The improvement in the $\\mathbf{R} 2$ evaluation measure confirms the power of the model has to recognize the underlying pattern emphasis. By preventing the AR from reaching a local minimum with the contribution of the SVM branch, the hybrid model exhibits high robustness to forecast errors, and shows superiority in PV power forecasting applications.

    IEEE
    Underwater Acoustic Sensor Network (UASN) routing is difficult for several reasons. First, the UASN's energy consumption rises because the distance between nodes changes as it moves with the water current. The gathered scientific data packets are sent from the acoustic network to a receiving station on land. Second, there are difficulties with the underwater acoustic network, such as longer propagation delays and lower capacity because of danger. The biggest hurdle is inefficient data packet transfer between the UASN node and the onshore sink node. Finding a method that uses less energy is just the first step in reaching maximum efficiency. The underwater routing protocol has to be resilient in the face of connection failure brought on by extreme weather or power outages. The Modified Buffalo Optimization Algorithm is a novel optimization technique inspired by nature. The issues listed above may be avoided by using the Modified Buffalo optimization Algorithm that has been presented in this study. It was implemented in the NS2 simulator to evaluate the program's effectiveness and through its paces against the Chimp optimization method. In terms of throughput, packet delivery ratio, and power efficiency, the simulated results shows that the MBOA algorithm out performs COA Algorithm.

  • Direct Torque Controlled Induction Motor Drive for Electric Vehicles Application
    S. Thangalakshmi, M. Padmarasan, V. Sridevi, and K. S. Kavitha Kumari
    IEEE
    Manufacturers are now very interested in the motorization control of commercial Electric Vehicles (EVs). This paper describes an Induction Motor (IM) control methodology used in EV applications. Motor drive control is critical in EVs, and IM-based drives are better suited for EVs. For IM drives, there are essentially vector and scalar control techniques. Low performance is a disadvantage of the scalar control approach, but Direct Torque Control (DTC) is an excellent approach for IM speed control by effectively controlling the torque and flux. The alternating current (AC) is taken as a source and connected to a rectifier circuit. However, the functioning of the Voltage Source Inverter (VSI) with variable switching frequency might be determined by the availability of hysteresis controls for torque and flux. The DTC-controlled IM drive is developed in MATLAB/ Simulink tool and the performance of the motor is evaluated by the obtained results. The motor’s torque and speed response are examined.

    IEEE
    In recent times, the application of renewable energy sources (RESs) for power distribution systems has been growing at a steady pace. This advancement brings several advantages such as energy sustainability and reliability, easier maintenance, cost-effective and ecofriendly energy option etc. The application of RESs in maritime systems such as port micro-grids could improve energy efficiency and reduce the utilization of fossil fuels, which has resulted in harm to the environment. Ports have been contemplating on several initiatives to improve their energy efficiency by deploying different types of RESs based on power electronic converters applications etc. This paper presents a systematic review to provide renewable energy options for state-of-the-art, modern electrification and infrastructure of seaports taking into account some challenges such as the environmental aspects, energy efficiency enhancement, renewable energy integration, and legislative and regulatory requirements. A brief projection of future work on the same is also included.

  • Ship Recycling-The Need of A Life Cycle Approach
    Gopikrishna Chockalingam, K. Sivasami, and S. Thangalakshmi
    IEEE
    Having identified the potential hazard during the Ship recycling process, the Hongkong Convention mandates the inventory of hazardous materials for Ships above 500 GT. It also mandates the Ship recycling facility to have a Ship Recycling Plan based on the inventory of hazardous material. The Hongkong convention although addresses most of the issues in the ship recycling industry in the beaching method of ship recycling, it is silent over the issues pertaining to the downstream waste management. India has ratified the Hong Kong convention on 29th November 2019, has enacted the Ship Recycling Act, 2019 in line with the requirements of the Hong Kong convention. This paper analyses the key issues of concern in the ship recycling industry especially which employs the beaching method of recycling and the dire need of a Life cycle assessment approach in ship recycling, the process improvement of hazardous waste handling in the Ship recycling industry to prevent the accident occurrences, reduce the health issues to the workers in the ship recycling industry in addition to the pollution prevention aspects in the adjacent coastal areas.

  • Planning and coordination of relays in distribution system
    S. Thangalakshmi
    Indian Society for Education and Environment
    Background/Objectives: A protective relay should proficiently distinguish between fault, normal and abnormal environments. The prime aim is to plan and coordinate the relays effectively during power system faults. Methods/Statistical Analysis: ETAP simulation tool is adopted for appropriately operating the backup relays, after giving acceptable time discernment for operating the primary region relays. The optimal identification of relay settings for both Main and Standby Protection is achieved using Fault Current Limiters (FCL) and Coordination Time Interval (CTI). The distribution set-up of Surana industries is considered for the analysis. Findings: The early detection of fault and automatic cutting off of defected portion ensures high degree of protection and instigates proper planning in any power system network. Normally the distribution system protection involves both principal relays and standby relays. The whole distribution system is divided into numerous intersecting zones to guarantee complete protection. Protective relays must function only for the precise protection for which they are intended, without functioning for any normal and short term tolerable abnormal happenings. Hence, during the failure of primary protection, the backup relays provide protection after some indicated time interval. The modern power systems use distributed network wherein which insertion and removal of DG units are common. This disturbs the relay coordination and initiates frequent operation of standby relays. Deciding the proper time interruption for the working of backup relays decides the protection quality in distribution link. Application/Improvements: The protection coordination of distribution set-up of Surana industries are formulated in ETAP after getting the power flow results using Newton-Raphson algorithm. Results show improvement over the existing methods.


  • Congestion management by optimal allocation of facts controllers using hybrid fish bee optimization
    Thangalakshmi
    Science Publications
    The role of Independent System Operator (ISO) in the restructured power industry includes system control, capacity planning, transmission tariff and congestion management; the challenging task being minimizing the congestion. One of the popular techniques used to alleviate congestion is using Flexible AC Transmission Systems (FACTS) devices. The power system generally operates near its rated capacity in deregulated market because of intensive usage of transmission grids. So, the major issues that need to be addressed are improving the voltage profile and reducing the power loss in the electrical network. Motivation: The location of FACTS devices can improve the power flow in the line, maintain the bus profile and reduce the losses. However locating the ideal location is a NP problem. This study presents a novel heuristic method to determine the types of FACTS devices and its optimal location in a power system without violating the thermal and voltage limits. Power flow sensitivity index to find the optimal location of UPFC is suggested in this study. A hybrid fish bee swarm optimization is proposed which is based on Artificial Bee Colony (ABC) and Fish School Search (FSS) methods. This proposed algorithm is tested based on IEEE 30 bus system and line performances are studied.
