    Modeling and performance analysis of microturbine based Distributed Generation system, "a review"
    (2011) Gaonkar, D.N.; Nayak, S.
    Distributed Generation (DG) is predicted to play an important role in the electric power system in the near future. It is widely accepted that microturbine-generation systems are currently attracting lot of attention to meet users' need in the distributed generation market. In order to gain the benefits of interconnected operation of microturbine generation system (MTG) system with the utility network, their effective modeling and performance analysis are required. This paper presents the recent research efforts in accurate modeling of MTG System and the investigation on various issues related to their interconnected operation and control with the distribution network. © 2011 IEEE.

    Dynamic modeling and analysis of an isolated self excited induction generator driven by a wind turbine
    (2012) Sabhahit, N.S.; Gaonkar, D.N.
    This paper presents modeling, simulation and transient analysis of three phase self-excited induction generator (SEIG) driven by a wind turbine. Three phase self-excited induction generator is driven by a variable-speed prime mover such as a wind turbine for the clean alternative renewable energy in rural areas. Transients of machine self-excitation under three phase balanced load conditions are simulated using a Matlab/Simulink block diagram for constant, step change in wind speed and random variation in wind speed. © 2012 IEEE.

    Simple and accurate method of modeling Photovoltaic module: A different approach
    (IEEE Computer Society help@computer.org, 2013) Jena, D.; Ramana, V.V.
    This paper proposes a different method of modeling Photovoltaic (PV) System in uniform irradiance conditions. It provides a simple and accurate method of modeling PV system using a single diode model by considering series and shunt resistance. This model computes five parameters and is having better accuracy than the existing models in literature. The accuracy of the proposed modeling technique is validated by comparing the model with the experimental values and datasheet values. The proposed model can be extended for modeling the effect of non-uniform irradiance conditions on PV system and also to track the maximum power from the PV source under non-uniform irradiance conditions. © 2013 IEEE.

    Analysis of Leakage Current Mechanism in Supercapacitor with Experimental Approach
    (Institute of Electrical and Electronics Engineers Inc., 2022) Bairwa, B.; Pareek, K.; Sarvagya, M.; Yaragatti, U.R.
    In this paper, we evaluated the leakage current of super capacitor during self-discharge. A three branch electrical equivalent circuit model (ECM) is constructed to estimate voltage response and leakage current of commercially available 2.7 V 350F (BCAP350) double-layer capacitor (DLC). Experimental work carried out with two constant current charging segments 0.25 ampere, and 0.5 amperes. Simulated data shows good agreement with experimental results obtained at electro-chemical workstation CH760e with RMSE and MAE error up to 0.0633, 0.05715, and 0.0759, 0.04173 for 0.25 ampere and 0.5 amperes charging current, respectively. The results confirm that the ECM model is capable to simulate the complex terminal behavior of the super capacitor and provides the means to study its application as an energy storage device. © 2022 IEEE.
