“…dimmable lights) can be curtailed without rebound effects. In this case, a conventional bidding strategy can be adopted, without the necessity of specifying logical constraints and rebound information [19]. particular, having considered the free-of-cost reactive power flexibility, its optimal management allows the solution of a significant portion of distribution network problems (especially voltage issues) even in CSs with marginal DSO market involvement.…”

The continuously growing distributed generation and the business potential for demand response are gradually enabling significant provision of flexibility and reserve towards distribution networks. For this reason, transmission and distribution system operators need to coordinate their operation in order to develop efficient market arrangements that can help utilize all the resources capable of providing ancillary services. SmartNet project investigated the potential interaction schemes between network operators, together with the possible new services devoted to the optimal distribution grid management. This paper summarizes the main challenges in simulating complex electricity systems and flexibility markets for three European countries (Italy, Denmark and Spain) in 2030 scenarios. The simulation results are then analyzed using cost-benefit analysis and regulatory conclusions are deduced.

“…The solution provided by the simulator yields electricity nodal prices and dispatch volumes for participating DERs over thousands of nodes. The focus of this paper is on the design and implementation of one of the aggregation models, the Curtailable Generator / Curtailable Load (CGCL) aggregator (Marthinsen et al, 2017). This paper outlines the design of such a software aggregator agent, and discusses the lessons learned from simulating a more realistic large power grid system.…”

To evaluate aggregation models in the context of a power system, a software tool (the SmartNet simulator) has been developed to look at the impact of managing Distributed Energy Resources (DERs) on networks' technical operation (e.g. power flows and voltage levels) and simulates wholesale and ancillary services market conditions. This paper focusses on the design and implementation of one of the aggregation models that addresses the Curtailable Generator / Curtailable Load (CGCL) aggregator. The paper outlines the design of such a software aggregator agent and discusses the lessons learned in simulating a more realistic large power grid system. The aggregator is represented as an agent based object orientated model using a financed based buckets system to aggregate bids from up to 300,000 devices across 10-20,000 power nodes. The concept/implementation can be extended to include more sophisticated bidding strategies and to use multiple perspectives on tranches. Simulation and testing of such a large simulation system was challenging, and we have proved that it is possible to simulate the aggregation and clustering of different types of flexibility into a number of manageable bids in a timely manner.
