Strategic analysis of electricity markets under uncertainty: A conjectured-price-response approach
(2007-02-01)This paper presents a model to address generation companies’ medium-term strategic analysis (including yearly forecast and decision-making processes) based on a conjectured-price-response market equilibrium representation ... -
Strategic bidding in a competitive electricity market: A decomposition approach
(Sin editorial (Oporto, Portugal), 2001-09-10)Daily bidding is an activity of paramount importance for generation companies operating in day-ahead electricity markets. The authors have developed a strategic bidding procedure based on strochastic programming to obtain ... -
Strategic bidding in Colombian Electricity market using a multi-agent learning approach
(IEEE (Bogotá, Colombia), 2008-08-13)In this paper, a multi-agent model of an electricity market is proposed using the Agent-based Computational Economics (ACE) methodology. The proposed methodology for modeling the bidding price behavior of Generation Companies ... -
Strategic bidding in secondary reserve markets
(2016-07-01)Electricity markets are based on several sequential energy and reserve trading mechanisms to constantly maintain the balance between generation and demand. During the last years, reserve markets are getting much importance ... -
Strategic bidding in sequential electricity markets
(2006-07-01)Wholesale electricity markets can be organised into different types of markets—energy markets and ancillary services markets—that are cleared sequentially. The paper proposes a stochastic-optimisation model to obtain the ... -
Strategic bidding under uncertainty in a competitive electricity market
(Sin editorial (Funchal, Portugal), 2000-09-25)The electricity industry is suffering an intense process of deregulation and restructuring throughout the world. In many cases generation companies are summoned to submit bids in some sort of organized market where demand ... -
Strategic bidding under uncertainty using genetic algorithms
(Sin editorial (Funchal, Portugal), 2000-09-25)This paper presents a new approach based on Genetic Algorithms (GA) to find the optimal bidding strategies of a market participant. Uncertainty about competitors behavior is included in our model, which incorporates risk ... -
Strategic bidding under uncertainty: a binary expansion approach
(01/02/2005)This work presents a binary expansion (BE) solution approach to the problem of strategic bidding under uncertainty in short-term electricity markets. The BE scheme is used to transform the products of variables in the ... -
Strategic decision-making support for distribution system planning with flexibility alternatives
(2023-09-01)The ongoing power system transformation requires rethinking the planning and operation practices of the different segments to accommodate the necessary changes and take advantage of the forthcoming opportunities. This paper ... -

Strategic maintenance scheduling in an islanded microgrid with Distributed Energy Resources
(2017-07-01)This paper addresses passive and active preventive maintenance scheduling in an islanded microgrid with storage and renewable energy sources. At first, under a centralized framework, a single-level cost-minimization ... -
Strategic maintenance scheduling of an offshore wind farm in a deregulated power system
(2017-03-01)This paper proposes a model for strategic maintenance scheduling of offshore wind farms (SMSOWF) in a deregulated power system. The objective of the model is to plan the maintenance schedules in a way to maximize the pro?t ... -
Strategic management of multi-year natural gas contracts in electricity markets
(2012-05-01)Combined cycle gas turbine (CCGT) plants show some advantages, such as better economies of scale, or lower CO2 emission rates, in comparison to other technologies. In addition, due to their flexible operation, CCGT plants ... -

Strategies to fulfill medium-term objectives through short-term operation in competitive power markets
(Sin editorial (Bolonia, Italia), 2003-06-23)This paper presents two different approaches in order to guarantee that short-term decisions made by a generation company taking part in a wholesale electricity market are consistent with its operation objectives formulated ... -
Stress vs sputtering effects in the propagation of surface ripples produced by ion-beam sputtering
(15/12/2015)Under low energy ion irradiation, periodic features (ripples) can develop on the surfaces of semiconductor materials, with typical sizes in the nanometric range. Recently, a theory of pattern formation has been able to ... -
Stress-driven nonlinear dynamics of ion-induced surface nanopatterns
(2019-11-15)For many solid targets, like semiconductors, that become amorphous under irradiation by energetic ions, the outermost surface layer displays formation of asymmetric nanoscale ripples in macroscopic timescales. In contrast ... -
Stress-induced solid flow drives surface nanopatterning of silicon by ion-beam irradiation
(2012-12-01)Ion-beam sputtering (IBS) is known to produce surface nanopatterns over macroscopic areas on a wide range of materials. However, in spite of the technological potential of this route to nanostructuring, the physical process ...
