Abstract

The invention discloses a total power generation cost optimization accounting method, and relates to the technical field of power grid planning. In order to solve the deviation problem of power generation cost calculation, the method specifically comprises the following steps: collecting power generation fuel quantity of a generator set in a power plant in real time; obtaining the power consumption at each moment before the day; determining whether the power consumption at each moment before the day exceeds a threshold value or not; according to the collected power generation fuel quantity andthe heat value corresponding to the power generation fuel quantity, the current power generation quantity of the power plant is calculated; and determining a day-ahead power generation plan accordingto a predetermined power generation condition and the power consumption at each moment. Compared with the mode of calculating the power generation cost through the total power generation plan and theaverage power generation cost, the calculation deviation of the power generation cost is reduced; the method can achieve the reasonable overall planning of the in-furnace fuel quantity, the reasonable distribution of the steam quantity and electric heating load of the generator set, and the precise scheduling, enables a power plant to always operate at an optimal economic point, and achieves theenergy-saving purpose of the power plant.

Description

technical field [0001] The invention relates to the technical field of grid planning, in particular to an optimal calculation method for total power generation costs. Background technique [0002] The reform of my country's electricity market is in the stage of deepening. For the organizers of the electricity market, the key to maintaining the orderly operation of the electricity market lies in perfect market rules. The key point is how to restrict market members from using market power. The ability to manipulate prices. In order to maintain the stable operation of the electricity market and the electricity system, the electricity market supervision department needs to supervise the electricity market to prevent abuse of market power, collusion and other behaviors that disrupt market order. The transaction electricity forms the monthly total power generation plan or the annual total power generation plan of the power plant. In order to ensure the orderly operation of the power...
