1. A method of operating an electrical power grid, comprising:
collecting bids describing one or more electricity characteristics, by an operator, in an energy market from one or more electricity transmitters and one or more distributors, wherein at least one of the distributors includes interconnected distributed energy resources, the distributed energy resources intermittently providing electricity to their interconnected distributor; and
clearing in an operator day-ahead energy market model, by the operator, the energy market with consideration of a transfer limit on the electrical power grid to determine commitments of electrical power;
providing one or more electricity characteristics to the one or more distributors and to the distributed energy resources; and
causing a controlling of dispatch of the electrical power through the electrical power grid based on the commitments to capture impacts of the interconnected distributed energy resources while respecting the transfer limit on the electrical power grid;
wherein, in the collecting step, the one or more distributors prepares a projected feasible operation region of a corresponding distribution system and submits it to the operator, together with bids of distributed energy resources, the projected feasible operation region including one or more desired variables; and
wherein, in the clearing step, solutions to the one or more desired variables are sent to the one or more distributors.
