Demand response (DR) has received significant attention in recent years and several DR programs are being deployed and evaluated worldwide. DR systems provide a wide range of economic and operational benefits to different stakeholders of the electrical power system including consumers, generators and distributors. DR can be achieved through a number of(More)
Peak demand is a major challenge for power utilities across the world. Demand Response (DR) is considered to be effective in addressing peak demand by altering consumption of end consumers, so as to match supply capability. However, an efficient DR system needs to respect end consumer convenience and understand their propensity of participating in a(More)
Driven by the increasing demand, grid technology is entering the business market in form of utility computing, grid middleware and grid-enabled application. However, the business market is interested in complete grid solutions. This means that for a successful take up of grid technology on the business market the establishment of grid value networks is(More)
Grid technology offers numerous opportunities for the players involved. Despite the fact that the academic community has already exploited many of them, there is an evident reluctance from the business community to act likewise. Recent analysis reveals that the problem lies in overcoming certain business barriers rather than technological ones. At this(More)
Grid middleware provides the fundamental framework for the provision of Grid services. However, Grid middleware is complex software that consists of several modules. The modules for a specific grid middleware exhibit in many cases complementary features and are produced by different software providers. Thus, in order to provide a complete grid solution for(More)
Participatory Sensing concerns the sharing of sensor information within user communities, forming a body of knowledge that can be beneficial to the community itself, either directly or through specialized applications. We introduce a framework for a marketplace where such applications can sell and buy sensor information. We focus on the buyers’ side and we(More)
Demand Response (DR) is considered an effective mechanism by utilities worldwide to address demand supply mismatch and reduce energy consumption, peak load and emissions. Consumer participation is central to realize the full potential offered by DR programs. The communication between a utility company and consumers participating in DR is through DR(More)
Demand Response (DR) programs encourage consumers to adjust their power consumption in response to DR events such as changes in electricity prices or sudden peaks in demand. While significant savings can be thus achieved, the real success of DR programs depends on the incentive compatible participation of consumers and their timely response to DR signals.(More)
Demand Response (DR) has recently garnered great attention, with many DR programs being deployed and evaluated worldwide. They are hailed as a significant benefit enabled by the Smart Grid and an efficient method to engage consumers in managing their energy usage and reduce environmental impact and costs. But while the opportunities are great, challenges(More)
