Hi Siyamak,

look to this link we propose tools dedicated to the real time energy management and if you have more questions contact:  [email protected]

When demand is more than generation(third world), energy management could increased the revanue considerably, for the supply companies. Refer my paper,'Microprocessor based load sheding controller....'.

Thank you for your answers.

Hi Siyamak,

I recommend you to take a look to my paper : "Real time supervision for a hybrid renewable power system emulator", Section Hybrid power system supervision procedure.

http://www.sciencedirect.com/science/article/pii/S1569190X13001755

• Concerning control, in many literature cases, energy management strategies are based on the imposition of DC bus voltage around battery nominal voltage. Two thresholds around battery nominal voltage are set to limit the voltage fluctuations and prevent overloads and excessive discharge of the battery. Optimally bus voltage will be between these two thresholds (see Figure 10), unless, the power management will tend to converge to VBat Nominal voltage. Similarly, two safety limits (V Bat Max and V Bat Min) are defined to protect the system by sources disconnection with switches.

• Concerning rules implementation, many works use artificial intelligence tools for hybrid power system supervision rules development and implementation, like fuzzy logic supervisor or multi-agent systems, for instance. Fuzzy logic is a well-adapted tool to manage complex Hybrid Energy Sources because of the difficulty to obtain or to use precise models of these systems, and the difficulty to predict the behavior of the wind or the sun, load consumptions. However such methods :

1) are complex to implement with slow computing time and need powerful calculators,

2) require additional software tools (e.g. the fuzzy toolbox),

3) are suitable for problems with a multi-objective supervision and when there are many possible scenarios.

Thank you Dhaker,

But do you know any other method similar to fuzzy logic or multi agent systems ? with more reliability and optimality ?

Hi Asma,

thank you for your response, Do you think these tools can be appropriate for V2G problem ?

Hi Siyamk,

ePHASORsim is a real time solution for large scale power system simulations (e.g very large power grids with thousands of buses, generators, transformers, transmission lines, loads and controllers ) so you can use it for V2G problem in real time.
