Smart Energy Communities Power Capacity Firming and Grid Flexibility Services

International Conference on Automation, Quality and Testing, Robotics, 2022
Most renewable energy sources, while contributing to the goals of the European Union’s Green Deal to decrease the greenhouse gas (GHG) emissions, also create stability and control problems to power grids due to their variability. In order to handle this,

Grid and Market Services From the Edge: Using Operating Envelopes to Unlock Network-Aware Bottom-Up Flexibility

IEEE Power and Energy Magazine, 2021
The proliferation of distributed energy resources (DERs) at the edge of the grid, such as residential solar photovoltaics and batteries, has created the opportunity for aggregators to manage multiple customers (hereafter referred to as active customers ...

Flexibility as a Service

2009
The lack of flexibility is often seen as an inhibitor for the successful application of workflow technology. Many researchers have proposed different ways of addressing this problem and some of these ideas have been implemented in commercial systems.

Developing Flexible Service Portals

Seventh IEEE International Conference on E-Commerce Technology (CEC'05), 2006
Business processes that need consistency and flexibility require flexible workflows. This paper outlines first our methodology for designing and implementing such flexible service business processes. Second, it discusses tools to ease the specification and re-use of flexible service processes. Finally, it presents the methodology process.

Towards Flexibility in Transactional Service Compositions

2014 IEEE International Conference on Web Services, 2014
Complex services can be described by service compositions and executed by service orchestrations. Changing service compositions is a frequent requirement in practical settings. Changing the composition must not result in a violation of its functional or non-functional properties. Whereas functional aspects such as soundness have been studied quite well,

Runtime Protocol Binding: Flexible Service Integration by Means of Flexible Service Interactions

2008 IEEE International Conference on Services Computing, 2008
Dynamic and flexible service composition and interactionare a must in service oriented computing (SOC) scenarios. In this paper the authors present an extension to a previous work, the DENEB platform for the development and execution of Web processes, allowing Web processes to acquire and execute new interaction protocols at runtime. This makes DENEB a

Flexible Service Composition

2006
Both the agent and Grid communities develop concepts for distributed computing, however they do so with different motivations. This paper demonstrates how the flexible coordination technique of interaction protocols, from the field of multiagent communication, can be used to model the processes found in scientific workflow, a typical composition ...
