I have the utility-scale storage reecc model along with the wind turbine REGC. I want to plot the SOC level and Storage of electrical power during various contingencies scenarios. I will be grateful if somebody explains how to monitor SOC and storage power.

# ierr, L = psspy.windmind(40,'2', 'WELEC','VAR')
# psspy.var_channel([-1,L+4]    ,'REECC_VAR 40 2 Residual_Energy')
# ierr, K = psspy.windmind(40,'2', 'WELEC','STATE')
# psspy.state_channel([-1,K+6],'REECC_STATE 40 2 Energy_Output')

I wanted above code in the following format: (just example is given here)

psspy.windmind([4,2,40],"1",r"""WELEC""")
psspy.state_channel([5,2,40],"1",r"""WELEC_STATE""")

Comments

The commented code seems ok. I don't understand what you mean with the "wanted" code.

Sorry for the late response. I am very thankful for the fast response. The problem I raised has been resolved as I used REECC to regulate the frequency following load shedding /generation trips. I simulate the frequency event; I have the following points to discuss: 1. I have enabled the frequency flag in REPCA, set the Dup and Ddn values, and the time required for charging/discharging. Also, I set the SOCinit to 0.65, SOCmax to 0.85 and SOCmin to 0.20. Doing so while simulating it is effective for downregulation (simulating load shedding). 2. In The same setting when I used for up-regulation (simulating generation trips), energy storage does not have any response to a frequency deviation. 3. Please put me some lights possible reasons if there are? What parameters must I look in order to perform up-regulation(Dup).
