Autonomous stably-supplying type renewable energy control device

An autonomous stably-supplying type renewable energy control device comprising:

• one or more a plurality of power converters connected respectively to one or more a plurality of power generation installations that each generate power from renewable energy,
• and having a proportional-control type power adjusting function that converts the power generated by the respective power generation installations from DC power into AC power and outputs the resultant power while adjusting the power to be outputted in proportion to a manipulation amount;
• a transformer;
• an instantaneous power detector that detects instantaneous power of the power outputted from the power converters;
• a voltage-phase-frequency detector;
• a generated power meter;
• a power transmission point that has interposed in order between it and the plurality of power converters, the transformer, the instantaneous power detector, the voltage phase-frequency detector, and the generated power meter;
• a comparison unit that compares the instantaneous power detected by the instantaneous power detector and a target value set by a to-be generated power setting unit and outputs a comparison signal;
• a control unit that adjusts the comparison signal outputted by the comparison unit;
• and
• an output signal unit that outputs the comparison signal adjusted by the control unit to the power converters as the manipulation amount, wherein:
• the to-be-generated power setting unit sets the target value based on a power generation amount setting value calculated by an information processing unit, and
• the information processing unit sets the power generation amount setting value such that the power to be outputted from the power converters is greater than a predicted power load but less than an actual power load when the actual power load is greater than the predicted power load, the predicted power load being a load predicted based on calendar information on a past power demand, the actual power load being a load that varies depending on actual weather information and a system voltage, phase, and frequency on an actual day.
