  • Flexibility Services Management Under Uncertainties for Power Distribution Systems: Stochastic Scheduling and Predictive Real-Time Dispatch
    IEEE Access, 2020
    Co-Authors: Vasileios A. Evangelopoulos, Iason I. Avramidis, Pavlos S. Georgilakis
    Abstract:

    Over the last years, the role of the distribution system operator (DSO) has largely expanded. This is necessitated by the increased penetration of intermittent energy resources at the distribution level, as well as the new, more complex interactions with the transmission system operator (TSO). As such, to properly manage its system and to have an effective joint cooperation with the TSO, the DSO is required to procure and carefully manage flexibility Services from distributed energy resources (DER). This paper introduces a thorough framework on optimal operational planning (day-ahead scheduling) and operational Management (real-time dispatch) of active distribution systems under uncertainties, to avoid line congestions and voltage limit violations, and efficiently balance the distribution system. A two-stage stochastic programming model based on weighted scenarios is proposed to optimize the multi-period optimal power flow day-ahead scheduling, i.e., scheduled power flows at the TSO-DSO interface and reserved DER flexibility Services. Subsequently, the operational Management, realized with a predictive real-time dispatch model based on a constantly updated rolling horizon, aims to efficiently activate the available flexibility Services to minimize deviations from the committed schedule. Different sources of flexibility are considered, with their respective response times also taken into account at real-time dispatch. The proposed framework is applied on two distribution systems and investigates the DSO's level of risk exposure while minimizing its total cost (reservation and activation expenses). The results indicate that a less conservative approach at planning stage, despite the potential risk exposure, can lead to significant reduction in total expenses.

  • BWCCA - Impact of Sharing Algorithms for Cloud Services Management
    Lecture Notes in Networks and Systems, 2019
    Co-Authors: Lidia Ogiela, Makoto Takizawa, Urszula Ogiela
    Abstract:

    In this paper will be presented a classification of sharing algorithms dedicated to secure Services Management in Cloud Computing. Especially will be described an impact of sharing processes in service protocols, realised in the Cloud. Service Management procedures can be used at different levels, so the impact of service Management processes will be analysed at all of them. Also will be presented the impact of service Management and cloud data sharing protocols, on decision-making processes in Management-support systems, using linguistic and biometric threshold schemes.

    Abstract:

    In this paper will be presented a description of service Management protocols for Cloud infrastructure. Especially, presented solutions will be dedicated to Cloud and Fog Computing. The main idea will be described with application of semantic aspects, dedicated to service Management application. Services Management protocols in the cloud and in the fog can be realized with application of secure and strategic methods.

  • Cognitive and Biometric Approaches to Secure Services Management in Cloud-Based Technologies
    IEEE Cloud Computing, 2018
    Co-Authors: Marek Ogiela, Lidia Ogiela
    Abstract:

    This article describes new ideas for applying security procedures to data and service Management in cloud and fog computing. Management in cloud computing is presented in connection with cognitive systems supporting Management tasks and securing important data. The application of cognitive and biometric features allows creation of personalized procedures oriented at particular users or a group of protocol participants.

  • ontological map of service oriented architecture for shared Services Management
    Expert Systems With Applications, 2014
    Co-Authors: Hai Wang, Shouhong Wang
    Abstract:

    Service oriented architecture (SOA) and shared Services (SS) have been widely studied in the information technology literature. However, there is a lack of tools for shared Services Management (SSM) to apply SOA. This paper proposes an ontological map for SSM to apply SOA. This mapping approach, based on the well-known Zachman framework of information architecture, specifies the ontological perspective of SOA for SSM. The ontological map semantically links all aspects of SOA for SSM. Through a case study, a design artifact of computerized ontological map of SOA demonstrates the usability of the artifact for SSM.

  • Differential QoS support in Web Services Management
    2006 IEEE International Conference on Web Services (ICWS'06), 2006
    Co-Authors: Abdelkarim Erradi, Srinivas Padmanabhuni, Niranjan Varadharajan
    Abstract:

    The variation of contexts in which a Web service could be used and the resulting variation in quality of service (QoS) expectations makes a clear case for further research to extend Web Services Management platforms with more sophisticated control mechanisms to cater for differentiated service offerings. However, most Web Services platforms are based on a best-effort model, which treats all requests uniformly, without any type of service differentiation or prioritization. This paper presents WS-DiffServ, a service differentiation middleware based on prioritization which leverages service requestor profile to classify service requests. We first explore the typical generic requirements of a differential QoS support in Web Services Management. We then present in detail the design of a priority based differentiated responsiveness platform for Web Services
