This report describes implementation of a Cloud-based control strategy for managing distributed energy resources on California’s electric transmission grid and electric distribution network. It is based on a connection of information networks with power networks to control distributed energy resources. The strategy is based on transactive energy-control techniques, which this project demonstrates to be a feasible and simple way to operate distributed energy resources.
This project assesses distributed energy resource control through a large-scale simulation model of the state’s electric system, including detailed modeling of distributed energy resources in residences. These distributed resources are primarily solar photovoltaic panels, home-storage systems, electric-vehicle chargers, and heating, ventilation, and air-conditioning systems. distributed energy resources are controlled through an auction-level market for agents participating in the market by distributing distributed energy resources DER output to the electricity network. A mathematical model of the system was developed to document the essential characteristics and behaviors of the electric distribution network. It was essential to assess and quantify different characteristics of the system including stability, stability robustness, and rejection of perturbations. Results from the large-scale simulation show the impact of multiple distributed energy resources on the system under different penetrations of renewable resources, as well as various operation conditions and capacity limits in the distribution network. Additionally, it allows both residents and utilities to compare renewable resource benefits. A small deployment of the hardware and the software in the City of Fremont has proved the feasibility of this Cloud-based strategy and operation of the communication and information exchange between distributed energy resources and the Cloud.
