Power Factory Digsilent Quasi Dynamic Simulation
Running Quasi dynamic simulation in Digsilent Powerfactory to test battery for load shifting. At first i was using QDSL battery model (power measurement type) from digsilent library but i dont get the expected result when i run the quasi-dynamic simulation, battery active power is constant zero. So i was then using simple way to model the battery, using negative load to function as battery when it's charging and static generator to function as battery when it's discharging. I used minus MW in time characteristic for the negative load and plus MW in time characteristic for the static gen. And then with that kind of model i got the result i want when i run the quasi-dynamic simulation. The Battery is charging when its low load and discharging when peak load.
Is it appropriate to model the battery like that?or should i using QDSL model?are there any spesific reference as how to modelling battery for load shifting/energy arbitrage?
