Dear Sir Zimmerman, We were using traditional 'C' programs those days developed by self and not much efficient.. to some extent one DOS based EMTP program frequently used in Universities..
(1 But I really appreciate the works done in matpower and power system analysis toolbox for power flow studies, which are dreams for me when I was doing my masters in power systems engineering around 15 years back. MATPOWER was first released about 12 years ago, so I'm not sure what you were using 15 years back.

No, you have not. (2) Matpower is mainly for power flow studies in a power grid , whether it is possible to include in matpower the study of auxiliary power supply systems in a typical power plant having diesel generators, power and auxiliary transformers and switchgears/ MCC, battery and Rectifier/ Inverter systems (3) As an example, I want to analyse sequential loading of diesel generators , change over transient of normal power supply to reserve power supply, load flow and fault analysis of auxiliary power systems in a nuclear power plant having components mentioned in point (2) As you mentioned, MATPOWER really is about power flow and optimal power flow in a power grid. Whether it can be used for other purposes depends entirely on how closely the model from your problem matches that of a traditional power grid.
