Joint Energy and Spinning Reserve Dispatching and Pricing
IFAC Proceedings Volumes, 2000Abstract Unpredictable load demand variations and also sudden generation interruption may cause imbalance in power systems. To prevent any blackout and to reduce such total power imbalance, spinning reserve can provide electric power system ability to respond.

The economics of commercial demand response for spinning reserve
Energy Systems, 2017Demand response (DR) for spinning reserve may be appropriate for customers whose operational constraints preclude participation in energy and capacity DR programs. We investigate the private business case of an aggregator providing spinning reserve in California across customer end uses and business segments. Revenues are calculated using end use level

Fast demand response as spinning reserve in microgrids
Mediterranean Conference on Power Generation, Transmission, Distribution and Energy Conversion (MedPower 2016), 2016Paper presents Fast Demand Response (DR) as readily available (i.e. sub-second) spinning reserve. As such it contributes to overall power system reserve and consequently increases renewable energy (RE) penetration. Paper outlines an implementation of Fast DR and presents measurements from a real isolated power system in Australia.

An Electricity Market With a Probabilistic Spinning Reserve Criterion
IEEE Transactions on Power Systems, 2004This paper addresses the problem of reliability-constrained market-clearing in pool-based electricity markets with unit commitment. In general, probabilistic reliability criteria that implicitly set the reserve requirement are defined by the loss-of-load probability and by the expected load not served.

Spinning Reserve from Hotel Load Response
The Electricity Journal, 2008Even though preliminary tests were not conducted during times of highest system or hotel loading during the summer, they showed that hotel load can be curtailed by 22 to 37 percent depending on the outdoor temperature and time of day. Full response occurred in 12 to 60 seconds from when the system operator's command to shed load was issued and the load

Spinning reserve opportunity cost in hydroelectric plants
IEEE Power Engineering Society General Meeting, 2005, 2005Starting from the deregulated process of the electric sector, there was the need to attribute responsibilities to several agents and to elaborate appropriate forms of remuneration of the services rendered by the same. One of the services of great importance within this new electric sector is the ancillary services.

Optimum allocation of spinning reserve by quadratic programming
Proceedings of the Institution of Electrical Engineers, 1975Quadratic programming offers attractive advantages as an optimisation technique in power-system optimumdispatch problems. A quadratic cost function can be minimised, subject to constraints linearised through sensitivity coefficients. If, however, there is a spinning-reserve requirement, the spinning-reserve characteristics of the individual generators ...

Optimal Scheduling of Spinning Reserve with Transmission Constraints
Electric Machines & Power Systems, 2000An effective method is proposed to schedule spinning reserve optimally. The method considers the transmission constraint in the whole scheduling process. To get the feasible solution faster, transmission line limits are first relaxed using the Lagrangian Relaxation technique.

Dynamic stability and network constrained optimal spinning reserve allocation
2011 IEEE Power and Energy Society General Meeting, 2011This paper presents an integrated work for regulation reserve allocation considering dynamic stability and load variations. In deregulated power system, participants compete to maximize their surplus without considering system stability margin, which forces the power system to operate closer to their instability boundaries.

Fuel Cost Modeling for Spinning Reserve Thermal Generating Units
2018 IEEE Canadian Conference on Electrical & Computer Engineering (CCECE), 2018In power system operations, the operating cost of thermal generating units is calculated based on polynomial functions of the units' power generation. Thus, they are applied only if these units are connected to the grid to serve the load. Spinning reserve units are kept running without committing them to the grid.
