Ancillary services network apparatus
First Claim
1. A method for providing ancillary services to an Independent System Operator (“
- ISO”
) or an integrated electrical utility by directing the operation of a plurality of resources selected from a group of controllable resources, each controllable resource having a primary process other than providing ancillary services and being either an on-line resource wherein its operational setpoints can be controlled to provide ancillary services by consuming or generating power within operational constraints of the primary process, or an off-line resource wherein its operational setpoints to consume or generate power are mandated by the primary process, the method comprising;
receiving a time varying ancillary services request signal from an ISO or utility;
receiving a time varying state signal of each controllable resource;
continuously selecting a cost-effective combination of the operational setpoints of the on-line and off-line resources that satisfy the time varying ancillary services request signal and the time varying state signal of each controllable resource, by selecting the operational setpoints of each on-line resource to consume or generate power to collectively provide the ancillary services as well as comply with the primary process of each on-line resource and compensate for power consumed or generated by each off-line resource, wherein the operational setpoints of each off-line resource to consume or generate power are mandated by the primary process of each off-line resource; and
continuously directing each on-line resource to operate at the selected operational setpoints and each off-line resource to operate at the mandated operational setpoints.

Abstract
An apparatus for providing Ancillary Services to an ISO controls multiple controllable resources over a network in a cost effective manner. The apparatus comprises a central server computer and multiple controllers communicative with the central server computer over a network. Each controller is located at a resource site and controls one or more resource devices. The central server computer has a memory with a program which executes the following operations: receives a services request signal from the ISO such as a Ancillary Services request, which requests a change in power consumed or supplied by the resources on the network; calculates the lowest cost means of delivering the requested Ancillary Services request; and sends setpoint control signals to the controller at each resource site where a change is needed, requesting a change in the operation of each resource device.
