After years of development and trial usage, cloud computing has finally entered into mainstream and wide spread commercial use. Among the various cost elements in operating a cloud computing infrastructure, power usage stands out prominently. In fact, how to reduce the power consumption of cloud computing platforms has received considerable attention of the cloud service provider as well as aca...

Given the load profile of an electricity market and the capabilities of the set of generators supplying power to that market, it is likely that at any given point in time, available supply will exceed demand. If only a subset of generators is required, some method is required to commit and de-commit generators. In the past, system operators have employed a centralized method of unit commitment....

This paper presents a study of the influence of the accuracy of hourly load forecasting on the energy planning and operation of electric generation utilities. First, a k Nearest Neighbours (kNN) classification technique is proposed for hourly load forecasting. Then, obtained prediction errors are compared with those obtained results by using a M5’. Second, the obtained kNN-based load forecast i...

The 95 percentile billing mechanism has been an industry de facto standard for transit providers for well over a decade. While the simplicity of the scheme makes it attractive as a billing mechanism, dramatic evolution in traffic patterns, associated interconnection practices and industry structure over the last two decades motivates an obvious question: is it still appropriate? In this paper, ...

The information and communications technologies (ICT) sector is seeking to reduce the electricity consumption of data processing centres. Among the initiatives to improve energy efficiency is the shift to cloud computing technology. Thanks to very favourable geographical conditions, the Canadian energy mix is highly suited to the implementation of data centres, especially in light of the signif...

Estimation of the load, particularly of the peak load, is basis for the system state estimation, and for technical, and economic calculations. This makes possible improvement in economic operation, maintenance of electrical equipment, and optimal planning and operating of electrical distribution systems. In the paper, starting from a fuzzy correlation model of the loads, a power flow analysis f...

For the purpose of aiding upper-level strategic or political decision making and some forms of conflict management, this chapter revisits the concept of dialectical inquiry (DI) from the perspective of collaborative framing or modeling for “collaboration engineering.” It does so by integrating the recent literature with its theoretical and philosophical sources. The connection of DI and the pro...

Electricity swing options are supply contracts for power, which give the owner the right to change the required delivery on short time notice. It gives more flexibility than fixed base load or peak load contracts. The name ”option” is a bit misleading, since it gives the owner multiple exercise rights at many different time horizons with exercise amounts on a continuous scale. We look at the pr...

Estimate of sediment load is required in a wide spectrum of water resources engineering problems. The nonlinear nature of suspended sediment load series necessitates the utilization of nonlinear methods to simulate the suspended sediment load. In this study Artificial Neural Networks (ANNs) are employed to estimate daily suspended sediment load. Two different ANN algorithms, Multi Layer Perce...

In this study, optimal allocation and planning of power generation resources as distributed with scheduling capability (DGSC) is presented in a smart environment the objective reducing losses considering enhancing voltage profile performed using manta ray foraging optimization (MRFO) algorithm. The DGSC refers to that can be scheduled their determined based on network requirements. main purpose...
