Power controller apparatus for power system including multiple customer facilities with battery apparatus

A power system including:

• a plurality of customer facilities connected with each other via a power network;
• and
• a power controller apparatus,
• wherein each of the customer facilities comprises a load apparatus, at least one of the customer facilities further comprises a power generator apparatus, and at least two of the customer facilities further comprise battery apparatuses,
• wherein the power controller apparatus comprises a predictor, an excess and deficient electric energy calculator, a group former, and a power transmitting and receiving controller,
• wherein the predictor predicts demand power of the load apparatus of each of the customer facilities in a unit time interval,
• wherein, for each of the customer facilities comprising the power generator apparatus, the predictor predicts generated power of the power generator apparatus of each of the customer facilities in the unit time interval,
• wherein, for each of the customer facilities comprising the battery apparatus, the predictor predicts inherent stored energy indicating stored energy of the battery apparatus of each of the customer facilities in the unit time interval, the inherent stored energy achieved when power is not transmitted to nor received from other customer facilities,
• wherein, for each of the customer facilities comprising the power generator apparatus and the battery apparatus, the excess and deficient electric energy calculator calculates excess electric energy generated by the power generator apparatus and not consumed by the load apparatus when the inherent stored energy reaches a first threshold, in the unit time interval, based on the demand power, the generated power, and the inherent stored energy,
• wherein, for each of the customer facilities comprising the battery apparatus, the excess and deficient electric energy calculator calculates deficient electric energy having to be supplied from other customer facilities when the inherent stored energy reaches a second threshold smaller than the first threshold, in the unit time interval, based on the demand power and the inherent stored energy, or based on the demand power, the generated power, and the inherent stored energy,
• wherein the group former combines at least one first customer facility and at least one second customer facility among the customer facilities comprising the battery apparatuses, the first customer facility having the excess electric energy in the unit time interval, and the second customer facility having the deficient electric energy in the unit time interval, whereby forming at least one group including the first and second customer facilities, and
• wherein, for each group including the first and second customer facilities, the power transmitting and receiving controller determines transmitting power from the first customer facility to the second customer facility, so that stored energy of each of the battery apparatuses of the first and second customer facilities is equal to or less than the first threshold, and equal to or more than the second threshold, over the unit time interval.
