Bilateral contract transaction among generation companies and large consumers is attracting much attention in the electricity market. A large consumer can purchase energy from generation companies directly under a bilateral contract, which can guarantee the economic interests of both sides. However, in pursuit of more profit, the competitions in the transaction exist not only between the compan...

A carbon emission trading self-scheduling (CETSS) model was proposed. The proposed considered not only allowance constraints but also trading. new method presented for solving CETSS problems based on piece-wise linearisation and second-order cone linearisation. effectiveness validity of the were illustrated by 10-100 unit systems over 24 hours.

This paper developed a stochastic programming model that integrated the most recent regulation rules of the Spanish peninsular system for bilateral contracts in the day-ahead optimal bid problem. Our model allows a price-taker generation company to decide the unit commitment of the thermal and combined cycle programming units, the economic dispatch of the bilateral contracts between all the pro...

This paper describes use of a new approach to solve multi-period multi-objective optimization of generation expansion planning problem in deregulated power systems over a long term planning horizon. Traditionally, the objective in undertaking aGeneration Expansion Planning (GEP) process has been tominimize the expected sum of yearly discounted costs(incorporate i.e., construction costs, operati...

We develop a constraint programming based heuristic algorithm using column generation technique to solve a ship routing problem which the loading and unloading times of cargoes at pickup and drop-off locations are significant. In order to prevent congestions at the locations, we need to assign berthing time slots to each vessel to perform the loading and unloading tasks at different locations. ...

The phenomenal growth of Internet service provider YouTube has already raised the company to legendary status. When Google acquired the company in 2006, YouTube’s founders became billionaires. But YouTube’s future success is contingent upon its ability to avoid copyright liability lawsuits that destroyed an earlier generation of online firms like Napster and Grokster. This paper describes YouTu...
