Integration of wind generation in Nordic-32 system
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.
Can you solve the load flow after adding the wind generation?
Yes, I am able to run load flow resulted in some mismatch at some far bus from the place where wind is integrated.
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.
Do you mean that all wind nodes go to code -2 or all machine nodes in the system?
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.
How many MW wind power have you added and how did you compensate for the increased generation? Is the swing bus generator overloaded?
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.
So how many MW are 20%???? You have to make a rough active power balancing yourself before solving. The swing bus will take care of the rest. In your case I guess too high burden is laid on the swing...
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
