1. A networked solar power generation plant system comprising: a plurality of solar power generation plants; and a power transmission network,
wherein each of the solar power generation plants is constituted by a plurality of solar power storage battery units, which generate and store solar electric powers and act as terminal units connected to the power transmission network via a power conditioner and each of which comprises: a power generation unit for generating electric power from solar light; a storage battery for automatically charging the electric power generated by the power generation unit therein; a communication controller for controlling discharge output of the storage batteries on the basis of instructions from outside,
wherein the solar power storage battery units are connected to an external management computer, by the communication controllers, via a communication network apart from a network for connecting to an electric power company through examined wattmeters such that the solar power storage battery units are virtually integrated as the networked solar power generation plant and are can be managed by the external management computer,
wherein the external management computer accesses to operating informations through an information network, the operating informations include:
identification informations for identifying each of the solar power storage battery units, the identification informations being given to the communication controllers;
specific informations of the solar power storage battery units including at least installation locations, the specific informations being linked to associate with the identification informations;
power storage informations of the solar power storage battery units including at least power storage amounts, the power storage informations being linked to associate with the identification informations, the power storage informations being variation informations; and
electric power demand informations being external informations relating to electric power demands, the electric power demand informations being variation informations,
wherein the external management computer produces a discharge output plan for each of the solar power storage battery units, on the basis of the identification informations, the specific informations, the power storage informations and the electric power demand informations, and controls discharge output of each of the solar power storage battery units such that electric powers stored in the networked solar power generation plants can be discharge-outputted, at optional time and in an optional amount, to the power transmission network, and
wherein the information network is provided such that the external management computer accesses informations of amounts of output powers, which are obtained by measuring output voltages and output currents of the storage batteries, with time, as an information of discharge output of each of the solar power storage battery units.
