I am a PhD student in Belém - Brazil (amazon) in the area of energy systems at PPGEE-UFPA. I intend to develop my thesis in the area of optimization for restoration of electric energy distribution systems with some goals and restrictions. My purpose is to develop an intelligent algorithm that performs a configuration in Electric Power Distribution Systems for the problem of restoration in both literature feeders and in the most complex (real), three-phase and unbalanced radial, with a multiobjective approach and with time requirements real. I have read several papers on the subject and intend to use MATPOWER to optimize the reconfiguration on some IEEE feeders (16,33 and 84 bars). Currently, I am starting programming and I have come up against a simple question regarding the manipulation of the (normally open and normally closed) IEEE cases of matlab (case33, case69, case84, etc), ie: How to manipulate the (Normally closed sections) and those to be closed for analysis (TIE keys)? Anyway, the reason for my contact is to know if anyone can help me regarding the switchings in the MATPOWER IEEE case files. That is, how do I manipulate (change the state of the keys)? For example, in the case of 33 bars, in the initial configuration, TIE keys are part of the initial configuration of the system. I do not know if I'm getting it wrong, but when running load (runpf ('case33')), whether or not you have the 5 TIE keys inserted in the case33 files, the result is always the same. I know I must be making a mistake, I just do not know what it is. I would appreciate the help.
