With the development of electric market, the interconnecting electric power system, whose purposes gradually transfer to market. And how to obtain the biggest economic performance becomes the main contents of study, and this brings up more and more high request for the problem solving. With consideration of the characteristics, the article introduces the genetic algorithm to the study of economic...
An interconnected transmission network of power system is composed of several subsystems which are jurisdictionally operated by different system operators and exhibit global changes instantaneously as a result of local decisions of any operator related to its own grid. The complexity of the coordination and decision making of power systems, an infrastructure which can be represented as a socio-technical...
This paper describes WECC's (formerly WSCC) experience in generator testing and model validation. WSCC introduced a generator testing requirement following failure of simulations to reproduce events that occurred in the summer of 1996 in the Western Interconnection. The benefits of generator testing have been indisputable. The generator model data has been improved significantly in many cases. It...
This paper aims at understanding and assessing the main methods proposed by ETSO and EuroPEX to define and allocate interconnection capacities in Europe. We model these methods and evaluate their technical and economic efficiency on a 7-node network. We find first, that, unsurprisingly, the allocation methods are all the more efficient as the Kirchhoff laws are integrated more precisely in the market...
This paper describing modellings and dynamic simulations of microturbine generation system (MTGS) in distribution system connected to multi-machines network. MTGS model is developed with the consideration of simulating a large number of these units in a large interconnected power system. Simulations are performed considering grid codes requirement. Dynamics of this integrated power system when subjected...
The desire to reduce harmful emissions from electricity production has led to an increase in the connection of renewable energy generation. Active network management (ANM) is one proposed method for allowing additional network connections without reinforcement of electricity networks. This paper presents a case study exploring the initial layers of a modelling and simulation framework for active networks...
The problem of cross border interchange and of allocation of exchange capacities between interconnected countries of the European Community has gained an ever increasing importance during the most recent years. The reasons for that are to be found in the existing price gap between different countries as well as in the limited exchange capacity of some interconnection corridors. As a result, the European...
The increasing amount of distributed generation (DG) located on distribution level is affecting the usage of the power system in different ways. The traditional planning and control schemes may become inoperative due to the contribution of DG. As the impacts of DG are significant and they are increasing rapidly, they should be better included in the planning systems and methods applied. Instead of...
One of the challenges connected with liberalization of the electricity market is the management of congestion in an interconnected network. Currently congestion management schemes employed in Europe vary from border to border. Due to the complexity of the network all of the schemes use a zonal approach where the whole market is split into hypothetical zones corresponding to countries. This paper has...
