This paper proposes a method for extending the ability of rotary power flow controller (RPFC) using tap-changer of the RPFC’s transformers. A detailed model of the device is presented to analyze the effects of the tap changer operation on the performance of the RPFC. To evaluate the results, the RPFC model is simulated using PSCAD/EMTDC software. Dynamic operation of the RPFC on a 400 kV transm...
Fault location is an interesting subject in power grids. On the other hand, the application of fault current limiter (FCL) has been increasing in power network and causes some problems in operation of protection systems. This paper studies the application of FCL in power system and its effect on one-ended simple reactance fault location methods. In these methods, only voltages and currents of t...
This project will develop (a) design theory and method for planning hybrid (discrete, continuous) power system controllers, and (b) economic systems, applicable to power system energy markets, for recovering and allocating costs of design and installation of such controllers. Discrete-event system theory and integer programming optimization methods will be used in the control design. The econom...
Unified Power Flow Controller (UPFC) is one of the most efficient FACTS devices that can be individually or combinatorial on all effective parameters in the transmission power of the transmission lines. With the flexibility of effective parameters in power passage, the power system operation can be improved. in this study, the optimization algorithm based on location and optimal capacity of UPF...
Economics views work as merely providing purchasing power. Many economists agree that there is a great deal more to work, but they nonetheless feel comfortable with this narrow description, believing that important aspects of work that they have left out of consideration have no impact on the validity of their analytical conclusions and policy propositions. This paper argues that if economics i...
Unlike perfect competitive markets, in oligopoly electricity markets due to strategic producers and transmission constraints GenCos may increase their own profit through strategic biddings. This paper investigates the problem of developing optimal bidding strategies of GenCos considering participants’ market power and transmission constraints. The problem is modeled as a bi-level optimizati...
Restructuring of electric industry has seriously affected the operation and planning process of electric power systems. Due to the unbundling process and new market requirements, a set of new challenges and goals have been introduced in the field of transmission planning. Moreover, the uncertainty level of input data to planning process has been increased significantly. In this paper first, the...
