Power systems require a certain amount of flexibility to meet varying demand and to be able to cope with unexpected events, and this requirement is expected to increase with the emergence of variable power generation. In this paper, we focus on gas e

Several demand response (DR) strategies rely on real-time pricing and selfish local optimization, which may not result in optimal electricity consumption patterns from the viewpoint of an energy supplier or a power system. Thus, this paper proposes a

A flexible demand-side can have a positive influence on electricity markets and the entire electricity infrastructure once the flexibility is properly harnessed. Such a goal is becoming attainable with emerging smart grid technologies which allow the

A great share of wind power generation in a power system is likely to test the system flexibility with extreme power ramp events. Therefore, this paper proposes a framework that allows the assessment of electricity demand flexibility on these events.

Open phase condition (OPC) is a situation where one or two phases of the feeding network are disconnected and the voltages become unbalanced. In a nuclear power plant (NPP), OPC can be a source of common cause failure and needs to be, therefore, care

Agent-based modeling of active distribution network helps to understand the dynamics and to design the control strategies for overall system efficiency. There is, however, a lack of generic and multipurpose agent definitions in existing studies. In t

Open phase faults can result in motor overloading due to unbalanced voltage. The present paper investigates different open phase conditions (OPCs) and their influence on an induction motor. The considered conditions include single and double line OPC

Forecasting errors in a power system occasionally leads to situations where either production or consumption is required to be altered. In order to improve demand-side contribution under these special conditions, this paper introduces an intra-hour c

Intermittent generation is challenging for the existing power systems, which have difficulties in following varying electricity production. To help the generation and demand be in balance, demand response (DR) provides one promising approach. Among m

The aim of this study is to develop a coordinated day-ahead voltage control strategy for an active distribution network. A framework comprising a synergy of real-time dynamic thermal rating (DTR) and coordinated voltage control (CVC) is proposed for
