In this paper we develop a possible notion of shortterm value-based reliability for operating an electric power network. As the electric power industry goes through the restructuring process, the operation based on the value-based reliability may be more appropriate than based on the traditional (N1) security criteria. The value-based reliability requires a framework where the factors to be con...

In this paper we present the development of a simulation model for large consumers to optimise their consumption and reserve offers in a security constrained electricity market. We utilise the New Zealand grid, which has security constrained generation and transmission which can influence marginal nodal pricing. To illustrate this influence we use a series of small optimal power flow models as ...

Energy management of virtual power plants (VPPs) directly affects operators’ operating profits and is also related to users’ comfort economy. In order provide a reasonable scheme for scheduling each unit the VPP improve VPP, this study focuses on optimization energy under premise ensuring flexible load users. First, loads are divided into time-shiftable (TL), power-variable (PL), interruptible ...

Computer systems often provide hardware support for isolation mechanisms such as privilege levels, virtual memory, or enclaved execution. Over the past years, several successful software-based side-channel attacks have been developed that break, at least significantly weaken, these offer. Extending a processor with new architectural micro-architectural features brings risk of introducing attack...

This paper presents a self-scheduling framework, using risk-constrained optimization model for the home energy management system (HEMS), considering fixed, controllable, and interruptible loads, as new contribution to earlier studies. The objectives are reducing electricity bill managing risk of purchasing over on-peak hours prosumer's discomfort index (DI) due shifting load undesired hours. In...

The growing interest with the developments of renewable sources owing to less environmental pollution creates challenges for grid operators. Virtual Power Plant (VPP) is a novel concept that will integrate small distributed energy resources and act as single conventional power plant in electricity market. As core management system VPP, should be dispatched optimally achieving maximum profit. Th...

In a smart grid, efficient load management can help balance and reduce the burden on national power grid also minimize local operational electricity cost. Robust optimization is technique that increasingly used in home energy systems, where it applied scheduling of household loads through demand side control. this work, interruptible thermostatically controlled are analyzed to obtain optimal sc...

Contract scheduling is a general technique that allows to design system with interruptible capabilities, given an algorithm not necessarily interruptible. Previous work on this topic has largely assumed the interruption worst-case deadline unknown scheduler. In work, we study setting in which there potentially erroneous prediction concerning interruption. Specifically, consider describes time o...

Smart home appliances can time-shift and curtail their power demand to assist side management or allow operation with limited power, as in an off-grid application. This paper proposes a scheduling process start time-varying deterministic load profiles. Self-triggered model predictive control is used limit the household net below given threshold. Meanwhile, profiles are more difficult schedule c...

ions like timeout are certainly difficult to get right, but fortunately they only have to be written once. We find that in practice dealing with asynchronous exceptions is fairly straightforward, following a few simple rules: • Use bracket when acquiring resources that need to be released again. • Rather than takeMVar and putMVar, use modifyMVar_ (and friends) which have built-in asynchronous e...
