I am looking for suggestions on DC-coupled hybrid Solar plus battery modelling. Could you please suggest models to be useful for the same.

I am trying to simulate generation loss that leads to frequency excursion. I would like to use REECC to respond to frequency decline to improve the frequency response. The following dynamic file for REECC and REPCA has been uploaded; please help me with which parameter could be modified or tuned in order to have the frequency response: Following data has been taken from google drive and shared by @jconto

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).

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""")

I am working on WTGIBFFRA (inertial-based fast frequency response model). I am looking for literature and WECC documentation to take forward my study. Please provide me with some lights on the same.

Hii All, I am trying to generate the .seq file for converting the network into RSCAD. So, please suggest me how I can get the sequence data in PSSE.

I am trying to model a diesel generator in PSSe. But I am getting confused about which generator model, exciter and governor I should take. Your suggestion is highly appreciated !

The following graph shows a frequency response from the simulation of the RVS Test Grid. I have simulated it but I observe that in the frequency graph in Y-axis the scaling is being repeated. I tried to fix it but was not able to do it. So, please help me to resolve it SUCH AS 0, 0.1,0.1,0.1,0.2,0.2,0.2...... Due to some reason I cannot attach figure here

Hi, I am working on renewable integration in PSSE, I am facing issues while putting more renewable in the network. After few percentages of RE penetration, there are some flanks (spikes). I am trying to understand dynamic data given in the PSSE manual and found data for WT4G1 and WT4E1 which is suitable for up to 2.5 MW wind capacity. But I am testing more than 2.5 MW around 500-900 MW wind, including Hydropower. I am looking for help!

I am looking for help. I have run the network in PSS/E through python. I got the initial condition, OK but afterwards, it is saying that not open for physical access. I tried to resolve it but fail to resolve it.
