Abstract:
A system, method, and computer readable medium for managing energy supplied by an electricity vendor to a facility heatable by electrical and non-electrical means are disclosed. The method, for example, involves determining a requested load from a vendor as the difference between a target load of the vendor and a current load on the vendor imposed by the facility; and when the requested load is greater than zero, increasing heating of the facility by electrical means thereby increasing a current heating electrical load of the facility by at least a portion of the requested load; and decreasing heating of the facility by non-electrical means thereby decreasing a current heating non-electrical load of the facility.
Abstract:
A method of managing energy supplied to a facility comprises monitoring a marginal cost of electricity from an electricity vendor; and determining a facility non-heating electrical load and a facility current heating load. The method also comprises obtaining fuel to supply energy to meet the heating load when the marginal cost of electricity is greater than a marginal cost of fuel or the non-heating electrical load is greater than a peak billed demand threshold. When the marginal cost of electricity is less than the marginal cost of the fuel and the non-heating electrical load is less than the peak billed demand threshold, electricity is obtained for the electricity vendor up to the peak billed demand threshold to supply energy to meet at least part of the current heating load, and fuel is obtained to supply energy to meet any current heating load not met by energy from the electricity.
Abstract:
A cost-effective method of heating a space in a facility comprises: (a) determining a cost of electricity from an electricity vendor; (b) when the determined cost of electricity is below an electricity pricing setpoint, obtaining sufficient electricity from the vendor to heat a heatable material such as water above a first temperature setpoint; and (c) when the heatable material has a temperature above the first temperature setpoint and a space requires heating, heating the space using at least some of the heat stored in the heatable material. Such method is particularly cost-effective when using electricity charged at a time-of-use basis.
Abstract:
A method for providing a local primary frequency response within a local region of an electrical power system uses one or more local load resources electrically coupled to the power system within the local region. The method comprises: determining one or more local frequency characteristics of the power system within the local region; determining an emulated inertial response for each local load resource based upon the local frequency characteristics; determining a desired local primary frequency response for each local load resource based upon the emulated inertial response determined for each local resource; determining operational setpoints for each local load resource to provide the desired local primary frequency response for the local resource; and directing the local load resources to operate at the selected operational setpoints for each local resource.
