An ac micro grid mainly consists of distributed generators an energy storage system and loads where the coordinated power management between these elements should be properly done in order to ensure efficient utilization of renewable energy resources. Since the renewable energy sources are inherent sources of supply the energy storage system plays an important role in managing the power flow between each and every elements of the microgrid by keeping the SoC of the ESS under safe region. In this study an autonomous power flow is proposed which is done through bus signaling method and the SoC conditions of ESS. The proposed control algorithm uses local controllers for regulating the bus voltage and frequency of the microgrid. Hence basic power management and voltage and frequency regulation is done within the microgrid. © 2016 IEEE.

Conference Paper

S. Manju, P.N. Seema, and A. Rajendran, “A novel algorithm for power flow management in Combined AC/DC microgrid”, in 1st IEEE International Conference on Power Electronics, Intelligent Control and Energy Systems, ICPEICES 2016, 2017.[Abstract]


A Combined AC/DC microgrid is established for the efficient power flow between AC and DC loads and the sources combining the advantages of both AC and DC microgrids. The AC and DC microgrids are merged through an interlinking converter (IC). Energy storage element is also connected to the system for providing continuous power supply. In this paper a new control algorithm for the bidirectional power flow control of interlinking converter during islanding mode of combined AC/DC microgrid along with battery control is implemented. The modified droop based control strategy eliminates the use of communication links and also reduces the power conversion stages. The input to the power management strategy are the frequency of the AC microgrid and the DC bus voltage of interlinking converter. The experimental simulations are performed in MATLAB/ SIMULINK and results are analyzed. © 2016 IEEE.

Conference Paper

A. Varghese, R.Chandran Lekshmi, and A. Rajendran, “Power flow control of solar PV based islanded low voltage DC microgrid with battery management system”, in 1st IEEE International Conference on Power Electronics, Intelligent Control and Energy Systems, ICPEICES 2016, 2017.[Abstract]


The use of low voltage DC microgrids is a promising concept that makes improvements in power quality and reliability to end users through different control techniques. A coordinated control strategy is addressed within DC microgrid for proper power management between sources and loads and regulation of DC bus voltage. For this; different modes of operation are performed based on state of charge of battery and DC bus voltage. Droop control is an effective solution for power sharing between solar PV; battery and loads. A separate control strategy has been developed for battery charging and discharging. MATLAB/SIMULINK simulation results are presented to demonstrate the effectiveness of the proposed power control strategy with battery management system during various operating conditions. © 2016 IEEE.

Conference Paper

D. G. Philip and A. Rajendran, “Development of a Multi-characteristic Distance Relay”, in Proceedings of IEEE International Conference on Technological Advancements in Power and Energy, TAP Energy 2015, 2015, pp. 176-181.[Abstract]


Distance relays are the vital protective device used for the protection of power transmission lines. The paper presents the development of a numerical distance relay, based on characteristics for the transmission line protection. The relay is developed on the conic and quadrilateral characteristics. It is intended to combine both the characteristics, so that, the protection scheme would exclude most of the conditions for which tripping is undesirable (arc resistances and power swings). The Conic - Quadrilateral characteristics have been plotted and the relay is tested by injecting faults. The developed characteristics contained the faults that occurred within the reach of the relay setting. The relaying logic is coded in MATLAB and the transmission system is simulated in Simulink. The result shows that the Multi Characteristic relaying scheme is highly suitable for protection of medium, high and extra high voltage transmission line during faults. © 2015 IEEE.

Conference Paper

S. A. V. and A. Rajendran, “Performance enhancement of PV arrays under partial shading conditions using SEPIC converter”, in Computation of Power, Energy, Information and Communication (ICCPEIC), 2014 International Conference on, 2014.[Abstract]


Conventional techniques fail to guarantee successful tracking of the global maximum power point under partial-shading conditions. This results in significant reduction in the power generated as wells as the reliability of the photovoltaic energy production system. For the effective utilization of solar panel under partial shading condition, global maximum power point tracking method (GMPPT) is required. This paper discusses an improved perturb and observe technique for tracking global maximum power point of photovoltaic arrays that has better performance even under partial shading condition than the conventional tracking algorithms. Initially GMPP is located by adjusting the control signal and then the control moves to local MPP stage. For the present study, single ended primary inductance converter is used as the dc-dc interface for MPP Tracking. This is a buck-boost derived converter which is better suited for photovoltaic applications than conventional buck-boost converter. Solar panel has been modelled and partial shading effects are implemented. Simulation results showing the performance of modified algorithm are presented with the help of MATLAB/Simulink. More »»

A. Rajendran, M.V.K. Kiran, Vasudevan, S. K., and A. Baskar, “An exhaustive survey on human computer interaction’s past, present and future”, International Journal of Applied Engineering Research, vol. 10, no. 2, pp. 5091-5105, 2015.[Abstract]


Technology has grown so much that interactions can happen even between computers and humans. The study related to this filed is called as HCI (Human Computer Interaction). It is more of an inter-disciplinary domain consisting of Computer Vision, Augmented Reality, Machine learning, Networking, Computer Graphics combined to build an effective computing system analysing the behaviour of humans as well as the computer technologies. HCI has simplified the human interaction with computers in the past, present and will always evolve till the end of time. Although the term HCI is in use since 1980’s, this field has come into limelight only after 1990’s. HCI deals with the design aspects of an entity which can be software or a product. It neither focuses on humans nor on the computers, but it certainly focuses on bridging the gap between the humans and computers. The main aim should be to develop a user friendly system rather than being confound. © Research India Publications.
