1. A method for determining by a utility energy consumer an estimated load for each time spot in a near-term proposed schedule set offered by a utility energy provider comprising:
receiving by said utility energy consumer said near-term proposed schedule set from said utility energy provider;
obtaining a historical resource usage, a historical unscheduled factors, a historical metering data and a prediction of near-term unscheduled factors of said utility energy consumer;
correlating said historical resource usage and said historical unscheduled factors to said historical metering data to produce a data structure;
using said data structure and said prediction of near-term unscheduled factors to produce a near-term load estimate;
wherein said near-term load estimate represents said estimated load for each time in said near-term proposed schedule.
2. The method of claim 1, further comprising mapping said near-term load estimate against a rate structure set provided by said utility energy provider to determine an optimal rate structure.
3. The method of claim 2, further comprising selecting said optimal rate structure from said rate structure set.
4. The method of claim 1, further comprising said utility energy consumer sending said near-term road estimate to said utility energy provider.
5. The method of claim 1, further comprising updating at least one of said historical resource usage, said historical unscheduled factors, said historical metering data and said prediction of near-term unscheduled factors.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An integrated electronic hydraulic brake system to transmit hydraulic pressure generated by pedal force of a driver to wheel cylinders, comprising:
an integrated hydraulic control device comprising a master cylinder having two hydraulic circuits to generate hydraulic pressure, a reservoir coupled to an upper part of the master cylinder to store oil, an accumulator to store a predetermined level of pressure, flow control valves and pressure reducing valves to control pressure transmitted from the accumulator to wheel cylinders installed at wheels of a vehicle, a pedal simulator connected to the master cylinder to provide reaction force of the brake pedal, and a simulation valve to control connection between the master cylinder and the pedal simulator; and
a power source unit comprising a pump to suction oil from the reservoir and discharge the suctioned oil to the accumulator to generate pressure in the accumulator and a motor to drive the pump, wherein
the power source unit is configured as a separate unit to remove noise generated from the power source unit, and the integrated hydraulic control device and the power source unit are connected to each other via an external pipe.
2. The integrated electronic hydraulic brake system according to claim 1, wherein the accumulator and the pump are connected to each other via the external pipe, and the external pipe has a check valve installed therein to prevent backward flow of pressure of the accumulator.
3. The integrated electronic hydraulic brake system according to claim 1, further comprising first and second backup channels connected between the two hydraulic circuits of the master cylinder and the wheel cylinders, a first shut off valve to control connection between the first backup channel and the master cylinder, and a second shut off valve to control connection between the second backup channel and the master cylinder, to control braking oil when the integrated electronic hydraulic brake system is abnormally operated.
4. The integrated electronic hydraulic brake system according to claim 1, further comprising a simulation check valve provided in a channel connected between master cylinder and the pedal simulator, wherein the simulation check valve is configured to transmit pressure generated by pedal force of the brake pedal to the pedal simulator only through the simulation valve.
5. The integrated electronic hydraulic brake system according to claim 4, wherein the simulation check valve comprises a pipe check valve having no spring to return the remaining pressure of the pedal simulator when the pedal force of the brake pedal is released.
6. The integrated electronic hydraulic brake system according to claim 1, further comprising pulsation attenuators provided in channels connected between the flow control valves and pressure reducing valves to control pressure transmitted to the wheel cylinders and the wheel cylinders to minimize pressure pulsation.
