ENERGY STORAGE MODELING AND CONTROL
First Claim
1. A computerized method for controlling a charge and a discharge of an energy storage asset in an energy storage system using a computer, the method comprising:
- receiving at the computer a first physical model for an energy storage application;
retrieving from a first database, using the computer, historical and forecast data related to an operation of the energy storage system;
receiving at the computer a configuration for the energy storage system;
receiving at the computer a cost model for the energy storage system;
receiving at the computer financial incentive information of serving the energy storage application;
receiving at the computer an operating strategy of the energy storage system;
receiving at the computer a second physical model for the energy storage asset;
calculating, using the computer, an energy storage asset charge and discharge strategy that maximizes the financial worth of the energy storage application, accounting for an energy storage system depreciation, based on at least one of the historical and forecast data, the first and second physical models, the financial incentive information, energy storage system constraints, the configuration, and the cost model; and
charging or discharging, using a controller, the energy storage asset according to the calculated charge and discharge strategy.

Abstract
Systems and methods for optimal planning and real-time control of energy storage systems for multiple simultaneous applications are provided. Energy storage applications can be analyzed for relevant metrics such as profitability and impact on the functionality of the electric grid, subject to system-wide and energy storage hardware constraints. The optimal amount of storage capacity and the optimal operating strategy can then be derived for each application and be prioritized according to a dispatch stack, which can be statically or dynamically updated according to data forecasts. Embodiments can consist of both planning tools and real-time control algorithms.
