| description | Embodiments of the invention provide a method and device for calculating an evaluation index of an ideal degree of operation economy of a power grid to solve the technical problem that an average electricity purchase cost index cannot truly reflect the service level of the scheduled operation. The method according to the embodiment of the invention includes the steps of performing optimal power flow calculation on each generator set according to operation data of a power grid to obtain an economy optimal operation position based on actual operation data of the power grid and a power generation curve of each generator set satisfying operation requirements of the power grid under the condition of the economy optimal operation position; calculating a first average electricity purchase cost corresponding to the optimal position of operation economy of the power grid according to the power generation curve and a preset grid purchase price, and calculating a second average electricity purchase cost corresponding to |
