Multi objective approach for tactical capacity management of distributed generation

Performance evaluation using periodic system-state measurements

This paper deals with the problem of inferring short time-scale fluctuations of a system's behavior from periodic state measurements. In particular, we devise a novel, efficient procedure to compute four interesting performance metrics for a transient birth-death process on an interval of fixed length with given begin and end states: the...

The effectiveness of throughput sampling for capacity management: A queueing approach

For effective capacity management in access networks, it is essential to have a good insight in the service quality perceived by the users. As users share the service capacity available, one would want to know how the achieved per-user throughput fluctuates over time. In this paper we present a novel method that assesses the per-user throughput...

The impact of QoS differentiation on service quality and system capacity in cellular networks

Mobile network operators are currently preparing the introduction of QoS differentiation mechanisms in their 3G networks, as a means to support service-specific quality requirements, to enable the offering of distinct subscription forms and/or to enhance the resource efficiency and hence network capacity. In this paper we quantify the attainable...

Performance/capacity gains from QoS differentiation in HSDPA networks: An operator perspective

Mobile network operators are currently preparing the introduction of QoS differentiation mechanisms in their 3G networks, as a means to support service-specific quality requirements, to enable the offering of distinct subscription forms and/or to enhance the resource efficiency and hence network capacity. In this paper we quantify the attainable...

The role of natural gas in smart grids

PowerMatching City (see ref. (Bliek et al., 2010)) is a living lab smart grid demonstration that shows the feasibility of a market based smart grid optimization methodology. It allows simultaneous optimization of multiple goals of the various stakeholders in a smart grid: in-home optimization, commercial optimization (VPP operation), congestion...
