This two-paper series proposes a novel deterministic optimization approach for the Unit Commitment problem (UC), more specifically for the Security Constrained Unit Commitment problem (SCUC) addressing thermal generating units. In the first part, a suitable mathematical programming model is presented, which contemplates all the inherent constraints and a single set of binary variables, i.e. the...

AbstractThe purpose of this paper is to highlight the positif significance site characteristics (shopping convenience, design, informativeness, security and communication) with e-WOM mediated customer satisfaction, e-trust e-commitment. The objectives research was : (a) positive effect shopping convenience (b) design (c) informativeness (d) (e) communication (f) satisfaction e-trust, (g) e-comm...

In this study, we investigated whether individuals’ personal and constraint commitment are differentially associatedwith their loneliness, as well as whether their commitment had an indirect effect on their stress through their loneliness. Participants included 255 couples in married or cohabiting relationships. Results of dyadic analyses indicated that individuals’ constraint commitment and lo...

Unit commitment (UC) is a optimization task planning operation in power system and is done by scheduled the generating units in on/off states. The UC problem is to minimize system total operating cost to meet forecasting load and reserve requirement while adhering to generator and transmission constraints to satisfy a given security level. The capability of using load, energy sources and energy...

The aim of this research is to investigate project commitment in the information systems security context. In doing so, a survey takes place in order to investigate organizational commitment to information security projects within a financial institution. Achieving the required level of information security within organizations usually requires more than security awareness and control but also ...

In the face of extreme events, e.g., hurricanes, transmission systems, especially lines, are affected across time and space. To mitigate these impacts on day-ahead market from a probabilistic perspective, resilient unit commitment (UC) problem is formulated as two-stage distributionally robust optimization (DR&RO) problem. first stage, commitment, energy, reserves generators pre-scheduled to mi...

Abstract Renewable energy has unpredictable intermittency and variability, increasing the complexity of grid dispatch. Fuzziness theory is introduced under uncertainty large-scale intermittent power supply. characterized by fuzziness parameters. Meanwhile, conventional deterministic unit commitment model transformed into a chance-constraint with The explicit equivalence classes chance constrain...

From the optimization point of view, an optimum solution of the unit commitment problem with reliability constraints can be achieved when all constraints are simultaneously satisfied rather than sequentially or separately satisfying them. Therefore, the reliability constraints need to be appropriately formulated in terms of the conventional unit commitment variables. In this paper, the reli...
