Operating reserve assessment has become increasingly important in the new utility environment in which ancillary services have been assigned a value and purchased in a competitive market. This paper first presents a procedure for compulsory provision of spinning reserve using a risk-constrained cost-based mechanism and then proposes a competitive market structure for spinning reserve procuremen...

A rapidly changing electricity sector requires adjusted and new ancillary services, which enable the secure reliable operation of system. However, assessments policy advice regarding services market design lack methods to evaluate complex interaction markets services. Therefore, this paper contributes an open-source agent-based model test options for markets. The Ancillary Services Acquisition ...

The Institute of Medicine noted that effective substance abuse treatment (SAT) programs integrate individual therapeutic approaches with transitional/ancillary services. In addition, research suggests that type of ownership impacts SAT services offered and that Medicaid plays a key role in SAT access. Data from the National Survey of Substance Abuse Treatment Services for the years 2000 and 200...

In order to ensure the quality of supply in the electric energy system the ancillary services frequency and voltage control are necessary. With regard to the ongoing decentralization of power supply, approaches are being investigated to provide those ancillary services by decentralized units some of which are highly volatile in power generation. This leads to the question of the reliability wit...

A variety of energy resources has been identified as being flexible in their electric energy consumption or generation. This energetic flexibility can be used for various purposes such as minimizing energy procurement costs or providing ancillary services to power grids. To fully leverage the flexibility available from distributed small-scale resources, their flexibility must be quantified and ...
