This work presents an enhanced multilayer second-order generalized integrator (EMSOGI) based control approach for a double stage single phase topology based solar PV array interfaced with the grid. This PV system is integrated into the grid at the DC bus of the voltage source inverter (VSI). The PV system satisfies the nonlinear load demand at the PCC (Point of Common Coupling) and feeds the excess power to the grid. The control is able to transfer the power even when the system is subjected to adverse grid conditions. The control is able to solve the inherent problems of the most popular controller used, that is, SOGI and its advanced versions. The boost converter is operated using a P&O (Perturb and Observe) algorithm to maintain the peak power point tracing from the solar PV module. Furthermore, the obtained results of a developed model in MATLAB SIMULINK platform are observed to show that the IEEE-519 standard is duly followed under various adverse grid conditions.

The uninterrupted power supply (UPS) system used in Indian Nuclear Power Plants (NPP) provides 415V three-phase four-wire supply to most critical loads. These loads are required for safe reactor operation, reactor shutdown as well as during accident conditions. Hence these UPS systems have very stringent qualification requirements. The newly proposed transient test as a part of qualification given in IEEE-650 is studied in this paper. This is based on the transient incident reported at the NPP of Forsmark, Sweden. The analysis presented here brings out the possible difficulties in carrying out this transient test. It also suggests possible design modifications that need to be addressed during the design of a power UPS.

This paper presents the analysis of real time power quality data collected for 50 days at a domestic site in India. The data is collected using a dedicated PQ analyzer. The measurement and analysis are performed to identify the level of different grid disturbances and compared with relevant standards. Voltage unbalance and individual voltage harmonics are observed to be the major disturbances. In addition, the analysis of different kinds of loads, including new technology loads, present at the house is performed by recording the current waveforms drawn by these loads. The incoming supply voltage and current of the neighbouring houses are also recorded. An aggregate load model is presented based on the measurements performed at different houses connected to the same feeder.

Maximum power point tracking (MPPT) technology is usually used in photovoltaic (PV) systems to extract the maximum power. Although the conventional MPPT techniques are easy to be implemented, they have to tune their control parameters by using trial-and-error method, which is not adaptive to different working conditions. Unlike the conventional MPPT techniques, the reinforcement learning-based MPPT (RL-MPPT) method has advantages of self-learning ability, which is better applicable performance under different weather conditions. To evaluate the RL-MPPT method, the simulations of Standard Test Conditions (STC) and varying irradiance conditions are performed.

A high conversion ratio bidirectional multi-mode DC-DC resonant converter for electric vehicle onboard charger with a notch filter function has been proposed. Due to different resonant modes (LLC and LLC-C) and gain characteristics of the proposed converter can provide a wide voltage gain range. Firstly, when operating at the higher voltage gain, it operates in LLC mode taking advantage of zero voltage switching (ZVS) on the converter and zero current switching (ZCS) on the output rectifier. Secondly, over the low voltage gain, the circuit operates automatically in LLC-C mode. This exhibits notch filter function providing infinite impedance (resonant zero point (RZP)), fast wide voltage gain regulation over a limited frequency range with good over-current protection. The proposed bidirectional converter is operating in both LLC and LLC-C modes. The analysis and design of the proposed converter are included in the paper. Additionally, closed-loop frequency modulation control simulation has been carried for charging during regeneration and discharging during motoring mode, which provides constant output voltage even if the input voltage and load are varying over a wide range. Thus, the proposed 1kW converter can inhibit the high conversion efficiency along with wide voltage gain, making the converter suitable for electric vehicle applications.

The technological development provokes the researchers to research in the field of the dual-port, multi-phase generating systems and machines with fine arrangement of magnetic poles for Higher Power Density (HPD) and reliable operation. Due to this, the authors opted for Dual Rotor Halbach Array Magnetic Pole De-Coupled Stator Six-Phase PMSG (DRHBAMPDCSSP-PMSG) and Dual Rotor Surface Mounted Magnetic Pole De-Coupled Stator Six-Phase PMSG (DRSMMPDCSSP-PMSG) for their investigation. The key motive of this research paper is concerned with the investigation of design and comparative analysis of Halbach array and surface mounted magnetic pole dual rotor de-coupled stator six phase permanent magnet synchronous generator for wind power application. To fulfill this objective, the Finite Element Method (FEM) is opted because of its high accuracy. Using transient and magnetostatic methods, the assessment of electromagnetic performances like Generated Voltage (GV), percentage (%) THD, electro-magnetic torque vs time, % torque ripple etc are investigated for both proposed generators.

This work presents an internal model control (IMC) scheme with one degree of freedom applied to regulate the output voltage of isolated dual active bridge DC-DC converter with voltage mode control. Internal model control structure is a model-based control predictive control structure and provides easy tuning to achieve the disturbance rejection and set-point tracking. IMC is designed using the linear model derived using generalized average modelling method around an operating condition. Simulation results are shown for a 100W, 20 kHz converter system to validate the IMC control, with different types of disturbances applied to the power converter to check its performance. Finally, the servo response and regulatory response of IMC are compared with the conventional feedback control approaches, K-factor approach-based controller and Proportional Integral (PI) controller in MATLAB/SIMULINK based simulations. The simulation results obtained reveal the strength and the efficacy of IMC by showing the better dynamic performance.

This paper studied the demand side management in smart micro-grid operation via conservation voltage reduction (CVR) application. A smart volt/VAR control approach has been introduced to enable the CVR operation. An event-driven realtime control approach has been proposed to check the effectiveness of CVR deployment. The impact of the community energy system (CES) in micro-grid operation and control has been studied by developing an adaptive volt/VAR droop control strategy for micro-grid CES (μCES) controllers. An accurate voltage sensitive load model has been utilized. The simulations have been carried out using a real-time digital simulator (RTDS) for three cases: normal operation, CVR operation, and cloud transient impact under CVR. Voltage fluctuation control under cloud transient has been further studied without controller, with conventional controller and in the presence of μCES controllers. The real-time simulation results validate the proposed control scheme, and results also reveal that CVR could reduce considerable peak power demand in micro-grid operation. Further, the μCES controller scheme handles voltage control smartly in comparison to conventional droop control.

This paper investigates the switching instability, also known as sub-harmonic oscillation of coupled inductor single-input dual-output (CI-SIDO) buck converter under peak current mode (PCM) control. The instability is predicted by developing an accurate small-signal model for PCM controlled CI-SIDO buck converter. The exact small-signal model is developed by using current modulator equations in the state-space model of CI-SIDO buck converter. The current modulator equations define the duty ratios as a function of the circuit variables and are the one that predicts the instability. It is observed that instability in CI-SIDO buck with PCM occurs when both or any one duty ratios are greater than 0.5. The instability is verified using MATLAB simulation results.

This paper presents a new super twisting sliding mode control for the isolated DC-DC bi-directional dual active bridge (DAB) power converter for enhanced output voltage regulation. The sliding mode control (SMC) is well known for its robustness and improved dynamics for non-linear systems. Still, it includes the drawback of high-frequency chattering and degradation of tracking performance. The suggested super twisting sliding mode control (ST-SMC) scheme incorporates the advantages of a sliding mode controller and eliminates the problem of chattering. Thus, improved dc-link voltage stability and high robustness for accurate reference voltage tracking are obtained. The output voltage in the DAB converter depends upon the power transferred through the transformer. The transferred power is a function of the phase shift of the voltage waveform of two H-bridges. The phase shift ratio is computed through the ST-SMC controller presented here utilizing the output voltage dynamic equation and power transfer equations for DAB converter. The proposed scheme which provides a robust control and an improved reference voltage tracking to the DAB converter performance. The proposed ST-SMC scheme is validated by simulation for 1 kW DAB converter in MATLAB-Simulink environment.
