EcoGrid 2.0: A large-scale field trial of a local flexibility market

摘要: Abstract The number of distributed energy resources installed in distribution networks is steadily increasing. Their flexibility can be leveraged by aggregators and used the wholesale markets. However, utilization this cannot neglect operating conditions networks, thus some form coordination between transmission system operators must exist. idea local markets has been proposed to address these issues, but experience from real-life demonstrations still missing. Danish project EcoGrid 2.0 designed, implemented tested a market with 800 participating customers, which runs parallel First, paper presents method identify quantify value possible services that are beneficial operator. Next, it provides insight operation real market, large controllable loads. Results show able reliably shape load residential heating units deliver services, despite presence uncertainties. Services act as an insurance policy against rare consequential network overloadings outages. In cases increase social welfare significantly. such should carefully selected avoid adverse effects. Finally, we provide guidelines general remarks on nature desirable characteristics those services.
