For many applications, it is important to evaluate trigger conditions on streaming time series. In a resource constrained environment, users’ needs should ultimately decide how the evaluation system balances the competing factors such as evaluation speed, result precision, and load shedding level. This paper presents a basic framework for evaluation algorithms that takes user-specified quality ...

A microgrid is composed of distributed power generation systems (DGs), distributed energy storage devices (DSs), and loads. To maintain a specific frequency in the islanded mode as an important requirement, the control of DGs' output and charge action of DSs are used in supply surplus conditions and load-shedding and discharge action of DSs are used in supply shortage conditions. Recently, mult...

Abstract With the continuous increase of wind power permeability, dynamic behavior system also changes, which has a great impact on setting low-frequency load-shedding scheme. The original scheme no good adaptability to high-permeability power. So, this article analyzes principles turbines in grid frequency control. This paper expounds principle strategy configuration. Connecting with actual op...

As a perspective to ensure the power system stability and to avoid the vulnerability leading to the blackouts, several strategies are adopted. In order to avoid the voltage collapse, load shedding schemes represent a suitable action to maintain the power system service quality and to control its vulnerability. In this paper, we propose a new approach of a load shedding strategy based on fuzzy c...

Clouds establish a new division of responsibilities between platform operators and users than have traditionally existed in computing infrastructure. In private clouds, where all participants belong to the same organization, this creates new barriers to effective communication and resource usage. In this paper, we present poncho, a tool that implements APIs that enable communication between clo...
