Abstract
A utility grid ancillary services system employs an inclined track with a utility grid connection system associated with the track. Shuttle units ride on the inclined track and have a motor/generator and an onboard electrical system for control. The motor/generator is connected to draw power from or provide power to the utility grid connection system. A controller in communication with an electric utility controls the onboard electrical system. Software modules in the controller increase uphill force responsive to a regulation down command from the utility thereby absorbing additional power from the utility grid or decreasing the amount of power provided to the grid. The software modules decrease force in an uphill direction responsive to a regulation up command from the utility thereby generating additional power to supply the utility grid or decreasing the amount of power absorbed from the grid.
