Batteries can be used to provide ancillary services, such as primary frequency response. However, their energy capacity is limited. Therefore, set-point adjustments are necessary and the energy for this has still to be provided by power-plants that do not face energy constraints. This paper investigates various aspects of and potential benefits for power system operation and stability, if energ...

This paper will present an e-procurement model to facilitate online B2B exchanges. Large organizations in Australia and around the world are increasingly implementing e-procurement, which has increased the need for services of intermediaries such as ‘emarkets’ to facilitate the process. However, both being new and unproven require theories and models to support their roles in the online procure...

As wind energy becomes a larger portion of the world’s energy portfolio there has been an increased interest for wind turbines to control their active power output to provide ancillary services which support grid reliability. One of these ancillary services is the provision of frequency regulation, also re­ ferred to as secondary frequency control or automatic generation control (AGC), which is...

Public procurement constitutes a large part of the market in many countries, and it has the potential of playing an important role in stimulating communities and serving policy goals. With this in mind the governments have set regulations for public procurement. Procurement of Information Systems is especially challenging due to the complexity of procuring unknown technology and the importance ...

In large parts of Europe, the development of healthcare is subject to contrasting forces: explosion in spending, while governments are faced with budget constraints, and pressures to be innovative, technologically advanced in order to improve the services’ quality. Even though e-procurement initatives can be seen as a solution to the first issue in this dilemma, such initiatives have not been w...

Public procurement or tendering refers to the process followed by public authorities for the procurement of goods and services. In most developed countries, the law requires public authorities to provide online information to ensure competitive tendering as far as possible, for which the adequate announcement of tenders is an essential requirement. In addition, transparency laws being proposed ...

The integration of renewable wind and pumped storage with thermal power generation allows for dispatch of wind energy by generation companies (GENCOs) interested in participation in energy and ancillary services markets. However, to realize the maximum economic profit, optimal coordination and accounting for reduction in cost for environmental emission is necessary. The goal of this study is to...

This study examines how individuals’ technology readiness in conjunction with organizational culture impacts on B2B customers’ behavioral intention toward using digital services in their procurement processes. We test our hypotheses with 755 B2B customers of a large Finnish supplier of furniture and interior solutions. We find that the propensity of individuals towards the use of technology, me...

This paper integrates Discrete Particle Swarm Optimization (DPSO) and Sequential Quadratic Programming (SQP) to propose a DPSO-SQP method for solving unit commitment problems ancillary services. Through analysis of services, including Automatic Generation Control (AGC), Real Spinning Reserve (RSR), Supplemental (SR), the cost model was developed. With requirements energy balance, operating cons...
