Resumen de: WO2026181603A1
In the power generation planning method for fuel cell equipment (40) including a plurality of fuel cell units (5), a provisional number (MPRO) of the fuel cell units (5) is determined. A power generation plan (XFC) for the fuel cell equipment (40) is created such that the number of the fuel cell units (5) generating power at the same time point in the power generation plan (XFC) is suppressed to a predetermined number (MCON) or less. When the provisional number (MPRO) is equal to or less than an upper limit number (MMAX), the predetermined number (MCON) is the provisional number (MPRO). When the provisional number (MPRO) is greater than the upper limit number (MMAX), the predetermined number (MCON) is the upper limit number (MMAX). The provisional number (MPRO) is the number of the fuel cell units (5) for covering a required generated power (P0) requested by a user from the fuel cell equipment (40). The upper limit number (MMAX) is an upper limit value of the number of the fuel cell units (5) generating power at the same time point in the power generation plan (XFC).
