I was wondering if you could help me out with a solar farm s

I was wondering if you could help me out with a solar farm simulation on Power World. I need to create a model of a solar farm and simulate the power output of the farm. I have never worked with this software before and have no idea where to start. The solar farm that the simulation needs to be based off is the Oregon Institute of Technology solar farm done by solar city. Even though solar city won\'t release any information on the system it self, I have provided 2 webistes that correspond to that specific solar farm.I really would appreicate it if you could point me in the right direction with an example or some step by step directions in how to develop this model. I would appreciate any help that I can get with this question. Please feel free to contact me with any questions as need. PLEASE HELP!!!!!

Thanks!

Solution

The details of renewable energy models have been explained in detail in PDF documents on the WECC website given below:

WECC MVWG Approved Model Specifications

In PowerWorld Simulator following combination of models can be used to model the various types of renewable generator models. .

Wind and Solar models in PowerWorld Simulator can be demonstrated as follows:

Here 6 Bus system has been used:

The case used in example in this example is as shown in the following figure:

In the figure 1, the left generator represents the renewable energy generator (bus 41905), while the right generator is modeled as an infinite bus (bus 41901) operating at a constant 1.05 per unit voltage and 60 Hz.

As an example, the following image (figure 2) shows what happens when you click Insert for Other Models on the Generator dialog’s Stability tab. (Given on Power tool website)

Once you have the models with you, Auxiliary Files given on website can be used You have to copy the contents of the zip file into its own directory, follow the given for transient stability demonstration:
