Demand Dispatch with Heterogeneous Intelligent Loads
For grid operators, this provides a scalable method to use demand-side resources for grid balancing, but the approach is incremental as it extends prior randomized decision rules.
The paper presents a distributed control architecture that enables heterogeneous loads to collectively behave like an ideal battery for grid operators, achieving a nearly flat input-output response.
A distributed control architecture is presented that is intended to make a collection of heterogeneous loads appear to the grid operator as a nearly perfect battery. Local control is based on randomized decision rules advocated in prior research, and extended in this paper to any load with a discrete number of power states. Additional linear filtering at the load ensures that the input-output dynamics of the aggregate has a nearly flat input-output response: the behavior of an ideal, multi-GW battery system.
