INTERNAL COMBUSTION POWER GENERATOR OPERATION CONTROL APPARATUS AND METHOD

PROBLEM TO BE SOLVED: To provide an internal combustion power generator operation control apparatus and method in which generation of NOx can be suppressed by avoiding output of an internal combustion power generator from becoming low in control of the internal combustion power generator in a micro grid.SOLUTION: An internal combustion power generator operation control apparatus 10 comprises a NOx suppression DB 51 which stores the quantity of generated NOx correspondingly to power generation output and weather data for each internal combustion power generator 101, and an operation record DB 52 which stores data about the situation of operating the internal combustion power generator 101 correspondingly to weather data of every time. A load amount in a micro grid 100 is predicted by referring to result data stored in the operation record DB 52, a power generation amount corresponding to the predicted load amount is determined and on the basis of the determined power generation amount and the quantity of generated NOx for each internal combustion power generator 101 stored in the NOx suppression DB 51, such a combination that output of the internal combustion power generators 101 to be operated does not become low to rapidly increase NOx is selected.
