Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations. This...

In the analysis of time series of blackouts a powerlaw dependency of blackout size with respect to frequency hasbeen observed. It has been hypothesized that this behaviour is theresult of the power system operating near critical points. Modelshave been created in order to analyze this type of...

In restructured electric power industries around the world, power pool designers have enabled generators to earn revenues consisting of energy and capacity payments. This paper discusses uses and abuses of capacity payments, and links provision of these payments to the issue of pricing...

Security in power systems refers to the ability of the system to withstand imminent disturbances (contingencies). Maintaining security is an issue which must be addressed at the system level. It is shown in this paper, however, that it is possible to maintain power system security in an...
