open source optimization programs
(OP)
dear forum members,
the electric industry is being deregulated in our country (philppines). soon we will be exposed to trading in the electricity pool. as a tool, i believe, is to have knowledge in optimization. i am familiar with power flow and wrote short codes in octave (looks like matlab). somebody told me optimization is more than just power flow. any suggested thread, website or existing codes to learn from, please. thanks in advance for all your responses.

RE: open source optimization programs
Not sure if I clearly get what you are asking for, but I think so. Optimization, or optimum power flow/load flow can often be performed completely separate from your load flow equations, although you will need to know the network demand. You also need to determine the cost/hr for operation of your generators, which is usually a non-linear function determine from experimentation/testing and then fit to a curve. Once you have done this, you would then use Lagrange multipliers to solve the system of cost functions for the solution that satisfies the following:
1. The net generation meets the net demand
2. The percent contribution for each generator minizes the cost of operation.
If you search for Optimum power flow/load flow, you should be able to find some sites with the matrices and equations using the Lagrange multipliers. I hope this helps and is what you were looking for.

I agree with Mstrvb19, this is a complex issue. You need to use a computational model which includes all the hydro, thermal players such as generators, IPPs, transmission and distribution networks etc. which determines the optimal operation of your network (least cost), This can affect your role in the system. Bear in mind that as a model it will give you the scenario of power flow, dispatching of generators, future demand, financial decisions etc. based on data feed to it; such as availability of water, restrictions etc. I suggest that you use a similar model as the regulatory agency as the algorithms used can vary from program to program and can give slightly different scenarios and lead to different solutions in the time.
I think this site can be very helpful: http://www.psr-inc.com.br it has lots of information, Papers, manuals, downloads etc. Generally these programs are complex and expensive, I suggest you check the internet of what suits your situation and budget.
Regards
