Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...
Widely-used operating systems provide inadequate support for large-scale Internet server applications. Their algorithms and interfaces fail to eeciently support either event-driven or multi-threaded servers. They provide poor control over the scheduling and management of machine resources, making it diicult to provide robust and controlled service. We propose new UNIX interfaces to improve scal...
To build a distributed operating system the mi-crokernel approach is the most popular. To build an adaptable operating system a minimal microker-nel is preferred. But for an adaptable and exible distributed operating system the previous approaches are not enough because they create an artiicial barrier to OS distribution and harm system transparency and adaptability. This paper express how adap...
In this paper, we design, implement, and evaluate a new scalable and fault tolerant network operating system, called ETTM, for securely and efficiently managing network resources at a packet granularity. Our aim is to provide network administrators a greater degree of control over network behavior at lower cost, and network users a greater degree of performance, reliability, and flexibility, th...
In this paper, demand response modeled with unit commitment in a nonlinear optimization problem, for increasing system security and economic reasons. By incorporating the demand response in the market it should decrease cost reduction, market clearing problems, congested lines and make a flat load profile at peak hours. In this problem, loads are combined of fixed and responsive loads. When thi...
Current differential based wide area protection (WAP) has recently been proposed as a technique to increase the reliability of protection systems. It increases system stability and can prevent large contingencies such as cascading outages and blackouts. This paper describes how power differential protection (PDP) can be used within a WAP and shows that the algorithm operates correctly for a...
in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...
