Abstract
Consumer battery installations are isolated, physical devices that are unable to participate in today's energy markets or other grid services outside what their vendor provides. Our recent work [5] describes a software system that manages multiple, networked battery energy storage systems in the electric grid. The system introduces two new ideas that enable flexible and dependable management of energy storage. The first is a virtual battery, which can either partition a battery or aggregate multiple batteries. The second is a reservation-based API, which allows dependable, asynchronous control of batteries to meet contractual guarantees.
This software system treats batteries as a single entity rather than as part of an integrated battery-solar system. As a result, batteries used in this software system charge/discharge at the exact rate specified by the system. Software management of multiple batteries within integrated battery-solar systems provides a new set of challenges that have not been addressed in prior work. We propose implementing a Proportional Integral Derivative (PID) controller to ensure that aggregate batteries maintain their desired outputs even with variable solar power from the integrated battery-solar systems.

Software defined grid energy storage
BuildSys '22: Proceedings of the 9th ACM International Conference on Systems for Energy-Efficient Buildings, Cities, and TransportationToday, consumer battery installations are isolated, physical devices. Virtual power plants (VPPs) allow consumer devices to aggregate for grid services, but they are are vertically integrated, vendor controlled systems (e.g., Tesla's VPP). Consumer ...
Battery management for grid-connected PV systems with a battery
ISLPED '12: Proceedings of the 2012 ACM/IEEE international symposium on Low power electronics and designPhotovoltaic (PV) power generation systems are one of the most promising renewable power sources to reduce carbon footprint. Grid-connected PV power systems do not generally have a battery to store the excess charge. However, due to severe imbalance ...
