Abstract
A method to calculate energy demand in an energy generation, transmission and distribution network including one or more power plants based on different energy source types including renewable energy, a communications system and one or more local consumption metering units. A customer demand profile for one or more customers is provided. A customer-specified proportion of power demand to be supplied from a given energy source type is registered. A total predicted energy demand dependent is calculated in part on an accumulated demand for the given energy source type.
Claims19
A method to calculate energy demand in an energy generation, transmission and distribution network, comprising one or more power plants based on different energy source types including renewable energy, a communications system and one or more local consumption metering units, the method comprising:
- providing a customer demand profile for one or more customers,
- registering a customer-specified proportion of power demand to be supplied from a given energy source type and a given supplier,
- registering a customer-specified maximum cost price profile,
- calculating a total predicted energy demand dependent in part on an accumulated demand for the given energy source type and the given supplier,
- determining available energy source types, demands for the available energy source types and cost price of energy for the available energy source types, and
- supplying energy to the one or more customers based on the customer demand profile, customer-specified proportion of power demand, customer maximum cost price profile, calculated total predicted energy demand, available energy source types, demands for the available energy source types and cost price of energy for the available energy source types.
A system to calculate energy demand in an energy generation, transmission and distribution network, comprising:
- one or more energy producing plants including plants based on renewable energy sources,
- a communications system comprising an energy demand profile for a power consumer and a maximum cost price profile for the power consumer, the energy demand profile including a customer-specified proportion of power to be supplied from a given energy source type and a given supplier,
- a calculation and algorithm system for calculating a total predicted energy demand dependent in part on an accumulated demand for the given energy source type and the given supplier, the calculation and algorithm system also for determining available energy source types, demands for the available energy source types and cost price of energy for the available energy source types, and
- means for supplying energy to the power customer in accordance with the energy demand profile, customer-specified proportion of power demand, customer maximum cost price profile, calculated total predicted energy demand, available energy source types, demands for the available energy source types and cost price of energy for the available energy source types.
A computer program product, comprising:
- a computer readable medium;
- and
- software code portions or computer program elements recorded on the computer readable medium and executable by a computer, a processor or a controller, to carry out a method comprising
- providing a customer demand profile for one or more customers,
- registering a customer-specified proportion of power demand to be supplied from a given energy source type and a given supplier,
- registering a customer-specified maximum cost price profile,
- calculating a total predicted energy demand dependent in part on an accumulated demand for the given energy source type and the given supplier,
- determining available energy source types, demands for the available energy source types and cost price of energy for the available energy source types, and
- supplying energy to the one or more customers based on the customer demand profile, customer-specified proportion of power demand, customer maximum cost price profile, calculated total predicted energy demand, available energy source types, demands for the available energy source types and cost price of energy for the available energy source types.
