In Doubly-Fed Induction Generator (DFIG), it is essential to maintain stator voltage and frequency at suitable value at every possible speed of rotor. Maintaining stator voltage and frequency is of utmost importance when DFIG operates in stand-alone mode to attain desired quality of power. It is also an essential condition in grid-connected mode for ensuring desired power flow. The primary route for controlling DFIG voltage and frequency at varying speed is through the Rotor Side Inverter (RSI). The present contribution reports modeling of RSI to control DFIG in real- time hardware-in-loop through MATLAB, Opal RT and associated hardware. Control parameters of the RSI are modulation index, rotor frequency, and switching frequency of the rotor of DFIG. Results at different wind speeds are observed both at open circuit and load connected condition. It is observed that at different wind speeds, judicious control of modulation index and rotor frequency enables maintaining 415V, 50 Hz at stator output terminals.

More than 30% of the world's energy consumption depends on building sector which causes 27% of total greenhouse gas emissions. More than 50% of this load is associated to space heating and cooling in buildings. The ground source heat pumps are used in building sector especially in harsh and warm climates, as a valid alternative to electric air-to-air/water heat pumps traditionally used to supply heating, cooling and domestic hot water loads. This study proposes an analysis on experimental basis of a ground source heat pump with a combithermal storage by means of real components and a hardware in loop test bed installed in a laboratory in Germany. The study will be conducted by using Second Law analysis of hardware in loop system allow to investigate different operating conditions and to identify the devices of the thermal plant that exhibit the largest exergy losses, efficiency defect and the greatest room for improvement. By considering an emulated constant thermal load equal to 5 kW for building during heating period, the ground source heat pump results the highest dissipative component of whole plant by destroying about 36% of exergy input in experimental test conditions which are a ground temperature of 6 degrees C, evaporator inlet temperature of about 0 degrees C and condenser water supply temperature of 46.8 degrees C. In this condition the heat storage exhibits an efficiency defect of 19.1% demonstrating that it is a strategic component for plant. A sensitivity analysis has been defined by varying on experimental basis the brine input to evaporator and water supply temperatures. The variation in the first parameter corresponds to a range on ground temperature from 5 to 25 degrees C while the second one allows to evaluate a range of supply temperature to storage of 35 - 60 degrees C. In addition, an exergoeconomic analysis has been conducted in order to evaluate the unit exergoeconomic product cost by showing that the exergoeconomic unit price of product for

This paper elaborates the real time simulation modelling of AC microgrid (MG) with various power generation sources (diesel generators, renewables, BESS, feeder, load, grid) and distributed control. This power system model is deployed in real time simulator, which is communicating with hardware's like physical secondary controllers, power meters, circuit breakers through the proper communication layers, power links, I/O device mapping etc. The main objective behind this HIL test bench is to model a complete smart MG system which is flexible scalable, secure, inexpensive, expandable. Also by using this, experiments such as control validation, communication tests, protection analysis, performance analysis can be done. Designed MG can operate in islanded, grid connected modes. We have validated the smart MG control functionalities like Peak lopping, renewable smoothing, BESS as a grid follower, Load sharing, automatic recharging etc. The experimental results shows that the proposed test bench is a useful tool to validate the control algorithms that can handle various uncertainties of real world in economical, effective way.

A hardware-in-loop real-time multi-simulation platform system is established based on data fusion approach, and the vehicle closed-loop control system is obtained based on "driver-central controller-motor drive system-vehicle dynamics," on which the control strategy of wheel-motor-driven multi-axle vehicle is verified. Data among the platform are transformed based on FlexRay bus. A simulation experiment of electrical vehicle dynamic performance is tested by real driver in real time to analyze whether vehicle dynamic performance is performed based on the multi-platform. The results indicate that the hardware-in-loop real-time simulation system can effectively verify the reliability of control strategy, and the data fusion of multi-simulation-platform works well.

hardware-in-loop (HiL) simulation focuses on testing of Electronic Control Units (ECU) in virtual real time environment in order to scrutinize the behavior of controller under test. Use of HiL simulation in development process reduces time and cost involved in verification and validation of the ECU's development. Generally, HiL systems developed using dSPACE (R), National Instruments (R) and other platforms used in automotive industry are very costly and sophisticated. For less complex systems a low cost HiL testing approach using an existing target hardware can be opted. It may or may not be possible to use existing hardware, as there might be limitations in the availability of pin count, onchip peripherals etc. This paper discusses a case study of Electronic Speed Limiter (ESL) where a low-cost HiL testing technique is being implemented for verification and validation of ESL. The ESL HiL system developed using existing target hardware can simulate different vehicle dynamics, driver behaviors, various road profiles and frictional coefficients in approximation to that of real time environment. The development process of a low cost HIL and research outcomes of ESL testing using the developed ESL HiL are discussed in detail. Developed simulation model increased scope of testing control logic of ESL. The results of HIL testing are found likely to "in-vehicle" testing and at same time controller under test is tested safely with low cost approach.

A Scalable Joint Estimation Algorithm for SOC and SOH of All Individual Cells within the Battery Pack and Its HIL Implementation

Accurately obtaining the state of charge (SOC) and health (SOH) of all individual batteries in a battery pack can provide support for data acquisition, state estimation, and fault diagnosis. To verify the real-time performance and accuracy of the joint estimation algorithm for high-voltage battery packs composed of 96 individual cells in series, this article applies Simulink to develop a joint estimation algorithm for SOC and SOH based on the first-order RC equivalent circuit model (1RC ECM) and implements the algorithm's cyclic calling for series nodes, enhancing the algorithm's scalability. In the algorithm, the recursive least square method with fitting factor (FFRLS) is applied to calculate OCV, R0, and R1 in the time domain, and dual adaptive extended Kalman filter (DAEKF) is applied to joint estimation of SOC and SOH at multiple time scales. Finally, with the help of dSPACE and FASECU controllers, hardware in the loop (HIL) testing was completed in multiple scenarios. The results showed that the algorithm can accurately calculate the state of individual cells in real time, and even under various initial value deviations, it still has good regression performance, laying the foundation for future applications of electric vehicles.
