The model uses Phasor solution provided by Specialized Power Systems in order to accelerate simulation speed. Description: The micro-grid is a single-phase AC network. Energy sources are an electricity network, a solar power generation system and a storage battery. The storage battery is controlled by a battery controller. It absorbs surplus power when there is excess energy in the micro-network, and provides additional power if there is a power shortage in the micro-network. Three ordinary houses consume energy (maximum of 2.5 kW) as electric charges. The micro-array is connected to the power network via a transformer mounted on a post which lowers the voltage of 6.6 kV to 200 V. The solar power generation and storage battery are DC power sources that are converted to single-phase AC. The control strategy assumes that the microarray does not depend entirely on the power supplied by the power grid, and the power supplied by the solar power generation and storage are sufficient at all times. Simulation: From 20h to 4h, the solar power generation is 0 W. It reaches the peak amount (5 kW) from 14h to 15h. As a typical load change in ordinary houses, the amount of electric power load reaches peak consumption at 9h (6,500 W), 19h, and 22h (7,500 W). From 0h to 12h and from 18h to 24h, battery control is performed by battery controller. The battery control performs tracking control of the current so that active power which flows into system power from the secondary side of the pole transformer is set to 0. Then, the active power of secondary side of the pole mounted transformer is always around zero. The storage battery supplies the insufficient current when the power of the micro-grid is insufficient and absorbs surplus current from the micro-grid when its power is surpasses the electric load. From 12h to 18h, battery control is not performed. SOC (State Of Charge) of the storage battery is fixed to a constant and does not change since charge or discharge of the storage battery are not performed by the battery controller. When there is a power shortage in the micro- grid, the system power supplies insufficient power. When there is a surplus power in the micro-grid, surplus power is returned to the system power. At 8h, electricity load No. 3 of an ordinary house is set to OFF for 10 sec by the breaker. A spike is observed in the active power on the secondary side of the pole transformer and the electric power of the storage battery.

Power & Energy Consumption Analysis of Hybrid Electric Vehicle (HEV) Wit...

This Video demonstrates how to generate MATLAB Live Script from Hybrid Electric vehicle multimode reference application.

Also can see how to evaluate and generate report for HEV - Power and Energy consumption analysis at the component and system level.

The live script provides: An overall energy summary that the script exports to an Excel® spreadsheet. Engine plant, electric plant, and drivetrain efficiencies, including an engine plant histogram of time spent at different efficiencies.

Data logging so that you can use the Simulation Data Inspector to analyze the powertrain efficiency, power, and energy signals.

The script uses the logged data to calculate efficiency, energy loss, energy input, and energy output for each component and subsystem.

Finally, the script provides an overall vehicle energy summary, a detailed subsystem summary, and Simulation Data Inspector time series plots.

Modeling & Analysis of Lithium - Ion Battery Pack with Fault using Matla...

This example shows how to simulate a battery pack consisting of multiple series-connected cells in an efficient manner.

It also shows how a fault can be introduced into one of the cells to see the impact on battery performance and cell temperatures.

For efficiency, identical series-connected cells are not just simply modeled by connecting cell models in series.

Instead a single cell is used, and the terminal voltage scaled up by the number of cells.

The fault is represented by changing the parameters for the Cell 10 Fault subsystem, reducing both capacity and open-circuit voltage, and increasing the resistance values.

Modeling & Analysis of Static Synchronous Series Compensator (SSSC)_ for...

This example shows a Static Synchronous Series Compensator (SSSC) used for power oscillation damping.

The Static Synchronous Series Compensator (SSSC), one of the key FACTS devices, consists of a voltage-sourced converter and a transformer connected in series with a transmission line.

The SSSC injects a voltage of variable magnitude in quadrature with the line current, thereby emulating an inductive or capacitive reactance.

This emulated variable reactance in series with the line can then influence the transmitted electric power.

The SSSC is used to damp power oscillation on a power grid following a three-phase fault.
