The unexpected and continuous changes of the workload reaching any Internet-based service make really difficult to guarantee a balanced utilization of the server resources. In this paper, we propose a novel class of state-aware dispatching algorithms that take into account not only the present resource load but also the behavioral trend of the server load, that is, whether it is increasing, dec...

In this paper, we continue to analyze optimal dispatch of generation and transmission topology to meet load as a mixed integer program (MIP) with binary variables representing the state of the transmission element (line or transformer). Previous research showed a 25% savings by dispatching the IEEE 118-bus test case. This paper is an extension of that work. It presents how changing the topology...

Particle swarm optimization (PSO ) is an effective & reliable evolutionary based approach .Due to its higher quality solution including mathematical simplicity, fast convergence & robustness it has become popular for many optimization problems. There are various field of power system in which PSO is successfully applied. Economic Load Dispatch(ELD) is one of important tasks which provide an eco...

Accurate power load forecasting has a significant effect on smart grid by ensuring effective supply and dispatching of power. However, electric data generally possesses the characteristics nonlinearity, periodicity, seasonality. For complex systems, presence redundant information potentially reduces real pattern extraction for forecasting. Bearing in mind these issues, we propose an model which...

Flight dispatching is the set of tasks related to flight preparation, such as load and balance, meteorology study and briefing, operational flight planning, contingency analysis and planning, etc. The flight dispatcher must be in close contact with the pilot in command in order to verify that the airplane is airworthy, furnishing all kinds of information needed to properly operate the system. T...

This paper presents a study to estimate the composition of an electric load, i.e. to determine the amount of each load class by the direct measurements of the total electric current waveform from instrument reading. Kalman filter algorithm is applied to estimate the electric load composition on a consumer side of a distributed power system. The electric load supplied from the different voltage ...

Towards the dual-carbon goals, new urban power grid (NUPG) dominated by energy has a low proportion of adjustable generation units, resulting in insufficient scheduling flexibility. As result, it becomes challenging to cope with complex operating conditions NUPG. In this paper, after analyzing operational characteristics and challenges NUPG, flexible load dispatching architecture key technologi...
