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...

In the paper load shedding time analysis in Buildings Energy Management Systems are presented. Influence of the communication system structures on the data exchange duration is analysed and its results for a few communication structures are presented. Streszczenie. W artykule przedstawiono analizy czasowe operacji redukcji obciążenia w budynkowych systemach zarządzania energią. Przeanalizowano ...

This paper presents preventive and emergency control measures for on line transient stability (security) enhancement. For insecure operating state, generation rescheduling based on a real power generation shift factor (RPGSF) is proposed as a preventive control measure to bring the system back to secure operating state. For emergency operating state, two emergency control strategies namely gene...

Energy is one of the basic requirements in modern civilization, without which various indispensable applications will bind to bring to a standstill. It is really not possible to measure the actual enormity of the function that energy has accomplished in connection with human advancement. As energy plays such a significant role in our day-to-day life, hence we should confer a precedence to accum...

A two-level adaptive load shedding scheme against voltage instability is proposed, adjusting its actions to the severity of the situation. The lower level includes a set of distributed controllers which curtail loads once the voltages at monitored transmission buses fall and stay for some time below threshold values. The adaptive nature of the proposed scheme comes from the upper level adjustin...

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 ...
