Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes
Advanced Optical Materials, EarlyView.We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

Optimizing the Spinning Reserve Requirements Using a Cost/Benefit Analysis
IEEE Transactions on Power Systems, 2007Spinning reserve (SR) is one of the most important resources used by system operators to respond to unforeseen events such as generation outages and sudden load changes. While keeping large amounts of generation in reserve protects the power system against the generation deficits that might arise from different contingencies, and thus reduces the ...

Model Identification for Spinning Reserve Management
2006 Canadian Conference on Electrical and Computer Engineering, 2006This Paper presents a model which facilitates the allocation of spinning reserve in a power network which includes a large HVDC infeed. The basic area control model of the power system is developed and subsequently fine-tuned using a non-linear optimization procedure. The model is then used to evaluate the frequency control performance in the face of a

Optimal scheduling of spinning reserve
IEEE Transactions on Power Systems, 1999Effective control of spinning reserve can provide substantial cost reductions in large power systems. This paper suggests that this goal can he achieved by tightly integrating a probabilistic reserve assessment with the unit commitment (UC) function.

This paper presents part of a more extensive work to solve the equilibrium point between the spinning reserve margin and the load shedding scheme as a consequence of generation failure so as to compensate economical transfers between generators and consumers. This paper analyses the effect of generation failures for different reserve levels considering

Reliability differentiated pricing of spinning reserve
IEEE Transactions on Power Systems, 1995This paper derives the spinning reserve pricing policy implied by the reliability differentiated pricing model and illustrates the importance of such a pricing policy. The purchase of additional spinning reserve capacity at the prices derived leads to benefits for the customers, through reduced real and reactive power prices and improved reliability of

Probabilistic spinning reserves with interruptible loads
IEEE Power Engineering Society General Meeting, 2004., 2004Effective participation of potential reserve providers such as interruptible loads in the power market environment would reduce the total offer cost. In the proposed market clearing process, both the reliability and performance records of the generators and interruptible loads are taken into consideration.

A methodology for management of spinning reserve requirements
IEEE Power Engineering Society. 1999 Winter Meeting (Cat. No.99CH36233), 1999This paper describes a methodology for management of spinning reserves involving, on the one hand, determination of system reserve requirements, and, on the other, determination of the availability of such reserves at any dispatch condition. Three types of reserves are maintained: primary reserves, intended to arrest the initial fall in frequencies ...

Interconnected System Spinning Reserve Requirements
IEEE Transactions on Power Apparatus and Systems, 1972There has been a considerable amount of work done in the area of static capacity reliability evaluation in interconnected systems. The first important paper in this subject1 utilized a two dimensional probability array upon which the tie line constraints were imposed.

Spinning and non-spinning reserve allocation for stochastic security constrained unit Commitment
2014 Power Systems Computation Conference, 2014This paper proposes a formulation for a stochastic security constrained unit commitment, dispatch and reserve scheduling, considering N-1 security and non-spinning reserves. We employ a randomized optimization technique that is based on scenario generation of the uncertain variables, in this case the wind power, and offers probabilistic certificates ...
