Nowadays, congestion management is one of the major tasks accomplished by system operators to warrant the operation of transmission system within operating limits. This has resulted in unanticipated congestion interfaces in regional transmission systems. The system is, however, unable to evolve at a rate which is required to meet the quickly changing demand of competitive markets. To make the m...

In this paper, we optimize train stopping patterns during morning rush hour in Japan. Since trains are extremely crowded, we need to determine stopping patterns based not only on travel time but also on congestion rates of trains. We exploit a Wardrop equilibrium model to compute passenger flows subject to congestion phenomena and present an efficient local search algorithm to optimize stopping...

Traffic congestion is one of the most serious problems that impact urban transportation efficiency, especially in big cities. Identifying traffic congestion locations and occurring patterns is a prerequisite for urban transportation managers in order to take proper countermeasures for mitigating traffic congestion. In this study, the historical GPS sensing data of about 12,000 taxi floating car...

ARTICLE HISTORY: Received 3 October 2015 Revised 23 December 2015 Accepted 3 January 2016 Under the smart grid environment, demand response resources (DRRs) are introduced as a virtual power plant which enhance power system adequacy. DRRs often fail to reduce their load due to some external factors. In this paper, a reliability model of a DRR is constructed as multistate conventional generation...

Competition is on rise in generation and distribution, which results huge transactions. Nonetheless, transmission lines are overloaded, since transmission system provides access of electricity having limited corridors. Consequently, the probability of congestion tends to be prominent. Congestion in transmission corridors not only causes collapse of that particular area but affects other area as...

Line outage security constraints ensure that a proposed generating schedule will not load any line to the point where its removal causes more overloading elsewhere. These increase operating costs by occasionally precluding usage of cheapest generation sources. That is, power networks frequently suffer congestion in this ($N-1$</inline...

Congestion and overloads in transmission lines always is one of the basic problems in the power system operation. Some of the consequences of this problem in the restructured power system are sudden price increasing in some areas, increase in market power and reduction in the competition in the market. FACTS devices as an efficient, powerful and economical means can have a key role in transmiss...

The power system becomes more severe under contingency conditions. In general, the contingencies may be outage of transmission lines or generators. To identify the effect of outages on system security, the contingency analysis is one of the analytical tools. The congestion on a system must be manages using generation rescheduling and with the proper control of the compensation equipments. The t...
