Hurricane events can cause severe consequences to the secure supply of electricity systems. This article designs a novel two-stage approach minimize hurricane impact on distribution networks by automatic system operation. A dynamic model is developed, which has variational wind intensity and moving path. The then presents resilience enhancement scheme that considers predisaster strengthening po...

This paper examines the operation of the Irish power system with very high levels of wind energy, with and without pumped storage. A unit commitment model which accounts for the uncertainty in wind power is used. It is shown that as wind penetration increases, the optimal operation of storage depends on wind output as well as load. The main benefit from storage is shown to be a decrease in wind...

The increasing penetration of non-synchronous, renewable energy in modern power systems displaces synchronous generation and affects transient stability. This is just one of the factors that has led to preventive curtailment of renewable energy sources in an increasing number of electrical grids. Transient stability constrained optimal power flow (OPF) techniques provide a tool to optimize the ...

BACKGROUND The Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) is a 24-item assessment designed to assist in the prediction of aberrant drug-related behavior (ADB) among patients with chronic pain. Recent work has created shorter versions of the SOAPP-R, including a static 12-item short form and two computer-based methods (curtailment and stochastic curtailment) that mon...

This paper addresses the optimal power generation and load management problems in off-grid hybrid electric systems with renewable sources based on appropriately constructed optimization problems. In this venue, the capacity and operating constraints for generating, storage and load units are first formulated as mixed-integer linear programming (MILP) models. In addition, we integrate the power ...

This paper analyzes multiple active management (AM) techniques of active distribution network (ADN), and proposes an optimal coordination model of intermittent distributed generation (IDG) accommodation considering the timing characteristic of load and IDG. The objective of the model is to maximize the daily amount of IDG accommodation under the uncertainties of IDG and load. Various active man...

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...

Seismic events can cause devastating impacts on both overground and underground energy system infrastructure. This paper proposes a methodology to evaluate the impact of seismic security integrated electricity gas system, mainly focusing pipelines leakage connection loss transmission lines. A stochastic model is used formulate damage level based earthquake severity. The classified according lev...
