Aggregated demand response for smart grid services is a growing field of interest especially for market participation. A growing trend in research is to utilize aggregated demand response for multiple smart grid services. This could be multi-market trading (day ahead, intraday and imbalance) or a combination of market and ancillary services such offering reserve power or congestion management. However,...
Previous and existing evaluations of available flexibility using small device demand response have typically been done with detailed information of end-user systems. With these large numbers, having lower level information has both privacy and computational limitations. We propose a black box approach to investigating the longevity of aggregated response of a virtual power plant using historic bidding...
Aggregated demand response for smart grid services is a growing field of interest especially for market participation. To minimize economic and network instability risks, flexibility characteristics such as shiftable capacity must be known. This is traditionally done using lower level, end user, device specifications. However, with these large numbers, having lower level information, has both privacy...
With the supply mix evolving to incorporate more and more uncontrollable renewable energy sources there is a need for more storage and demand response solutions. Aggregated demand response flexibility has been investigated in the past years as one of the potential solution this problem. This paper will investigate the potential impact on risks and gains for stakeholders using aggregated residential...
Agent based techniques are used to coordinate demand and supply for increasing the embedding capacity of dispersed, badly predictable, renewable energy based power systems. VPPs (Virtual Power Plants) using this technology have demonstrated their feasibility in field tests and currently are scaled up to satisfy requirements for massive rollout [1]. These agent-based VPPs mostly are used in normal...
Whereas other smart grid field trials optimize for a single objective, PowerMatching City phase 2 demonstrates that multiple objectives can be achieved in a coordinated virtual power plant. A system that incorporates both consumer community proposition incentives and trade dispatch incentives (as well as end-user comfort) was designed, implemented and tested. This paper describes the design approach...
Apart from the optimal real-time electricity price to buy the electricity, the optimal, time dependent, capacity contracted with the DSO is of crucial importance for concerted charging of electric vehicles in a parking garage. The battery management system, on its turn, imposes constraints on the sequence of steps in which power is transmitted. Maximum power in individual charging steps has to vary...
Response of demand, distributed generation and electricity storage (e.g. vehicle to grid) will be crucial for power systems management in the future smart electricity grid. In this paper, we describe recent results using PowerMatcher a smart grid technology that integrates demand and supply flexibility in the operation of the electricity system through the use of dynamic pricing. Over the last few...
Demand side management has traditionally been investigated for “normal” operation services such as balancing and congestion management. However they potentially could be utilized for Distributed Network Operator (DNO) services. This paper investigates and validates the use of a supply and demand response technology for secondary services, namely, frequency control.
Renewable energy sources and other types of distributed generation are becoming ever more present in todays power supply mix. In addition, a change in electric load is being seen with the increase in electric heating and electric vehicles. These additions may create a number of challenges in the current electrical grid. At DSO level problems in substation congestion and voltage and frequency instability...
Supply and demand response is a untapped resource in the current electrical system. However little work has been done to investigate the dynamics of utilizing such flexibility as well as the potential effects it could have on the infrastructure. This paper provides a starting point to seeing the potential flexibility available as well as the characteristics of a virtual power plant as a result of...

In this paper, we describe a smart grid technology that integrates demand and supply flexibility in the operation of the electricity system through the use of dynamic pricing. Over the last few years, this technology has been researched...
With the world becoming ever more conscious of the necessity for clean, sustainable energy sources, an increased proportion of energy produced by wind resources is expected. In the current power system, the integration of such large capacity of non-load-following and intermittent supply leads to several challenges, one of which is to control the balance between demand and supply. A large - not yet...
