PRIYANKA's profile - activity

I am trying to model the interruptible load for the dynamic simulation to analyse its impact on frequency deviation. How can this can be executed in PSS/E?

Earlier I was facing the issue of LF while integration wind generation in the system, now it is being solved using flat start. But while going for dynamic analysis, its shows initial conditions suspect for many of the conventional generator parameters along with WT3 model of wind. When moving forward to initializing and applying bus fault showing some values in the output bar after clearing fault running it for more of 10 secs, after 1 sec of clearing fault showing zeros under all heads. Kindly guide through this. I am not able to understand the reason behind same. While running the dynamic simulation without wind integration everything is running fine.

Thr is another prob while running LF using full newton raphson method, each time outcome is diff. Wid flat start & don't flat start result differs each time wid same data. Cn u plz guide with this. Sometimes LF converges very fast with 0MW mismatch and no violation, sometimes its show some mismatch

Penetration of wind is 20%. No extra compensation is done. I thought the generator would adjust their generation on their own. What compensating devices can be added to meet the system requirement.

more than 50% of machines including wind is going to -2. 1/3 wind unit is reaching this limit. Just want to know which parameter needs to be modified to get the desired outcome. When I am changing an angle and voltage PU of the buses whr Wind is connected, there occurs some change in power mismatch.

When I am integrating 20% wind generation connecting the machines at buses where neither machine nor load is connected earlier. All machine code goes to -2 after load flow. After this, I am not able to go for dynamic analysis as while going for switching studies pss/e stopped working.

Yes, I am able to run load flow resulted in some mismatch at some far bus from the place where wind is integrated.

While integrating wind generation by extending the bus results in many of the generating units reaching their reactive limit, after power flow codes of generators changed to -2. Can anyone guide me in this? Without integration load flow is running fine. I want to do the dynamic study by integrating the renewables and storage in the system.

I have performed dynamic simulation using bus fault at generator bus, as a result, the frequency rises just after the actuation of fault. I am not able to analyze the reason behind. Instead, if I would perform LLG or LG fault on the same bus, the frequency drops just after the fault. Further, I would like to know whether there is any other way by which plot using .outx file can be drawn at single y-axis rather than separate y-axis for each parameter in an individual sheet.

Thank you. I will try and implement the same.

What is the reason for behind this error and how it can be rectified?
