This article develops a distributed framework for coordinating distributed energy resources (DERs) in a power network to provide secondary frequency response (SFR) as an ancillary service to the bulk power system. A distributed finite-time protocol-based solution is adopted that allows each DER in the network to determine power reference commands. The distributed protocol respects information exchange constraints posed by a communication network layer while being robust to delays in the…

Scalable Hybrid Classification-Regression Solution for High-Frequency Nonintrusive Load Monitoring

Residential buildings with the ability to monitor and control their net-load (sum of load and generation) can provide valuable flexibility to power grid operators. We present a novel multiclass

Gradient-Consensus: Linearly Convergent Distributed Optimization Algorithm over Directed Graphs

TLDR
A "optimize then agree" framework to decouple the gradient-descent step and the consensus step in the distributed optimization algorithms is proposed and a novel distributed algorithm is developed to solve a multi-agent convex optimization problem.

Distributed apportioning in a power network for providing demand response services

TLDR
A distributed scheme is proposed that enables a DER in a network to arrive at viable power reference commands that satisfies the DERs local constraints on its generation and loads it has to service, while, the aggregated behavior of multiple DDERs in the network and their respective loads meet the ancillary services demanded by the grid.

Coordination and Control of Distributed Energy Resources for Provision of Ancillary Services

This paper discusses the utilization of distributed energy resources on the distribution side of the power grid to provide a number of ancillary services. While the individual capability of these

Distributed Energy Resource Coordination Over Time-Varying Directed Communication Networks

TLDR
This paper proposes an algorithm based on the push-sum and gradient method to solve the optimal DER coordination problem in a distributed manner and proposes an accelerated distributed algorithm with a fixed step size.

TLDR
This FERC Order 841 has its own challenges: some think FERC stepped on their toes, it does not address all the value stack benefits for storage-like transmission for example, and aggregation of distribution connected storage is side stepped.

Finite-Time Approximate Consensus and Its Application to Distributed Frequency Regulation in Islanded AC Microgrids

TLDR
The approach to achieving finite-time approximate consensus builds upon ratio consensus, a distributed iterative algorithm in which each node maintains two state variables where the ratio of the states converges asymptotically to a constant that is equal for all the nodes.

Reserve Policy Optimization for Scheduling Wind Energy and Reserve

The rapid increase in the integration of renewable resources has given rise to challenges in power system operations. Due to the uncertainty and variability of renewable generation, additional

Distributed Secondary Frequency Control Algorithm Considering Storage Efficiency

TLDR
A method for decomposing the target signal into a different signal for each generator and each storage unit, depending on their characteristics and on the storage energy levels, which is particularly suitable when the storage population varies by orders of magnitude.

Distributed frequency control for stability and economic dispatch in power networks

TLDR
Two different frequency control strategies are explored to ensure stability of power networks and achieve economic dispatch between generators and controllable loads and a distributed averaging-based integral control which operates by local frequency sensing and neighborhood communication is designed.
