Generation cost calculation method, device and storage medium for current markets

Abstract

The invention discloses a generation cost calculation method. The generation cost calculation method comprises the following steps that planned electricity consumption of historical moments is obtained; a historical power generation plan is determined based on predefined generation conditions and the planned electricity consumption; a real-time generation plan of a current day is determined by thehistorical power generation plan; and the generation cost is calculated based on the real-time generation plan and the real-time generation cost. According to the technical scheme, the real-time generation plan of the current day can be determined based on the historical generation plan, and therefore real-time generation is conducted according to daily electricity demand, and generation efficiency of various power plants is improved. The generation cost can be calculated based on the real-time generation cost. Compared with the prior art that the generation cost is calculated by a total power generation plan and the average generation cost, generation cost calculation deviation is reduced. The invention further discloses a generation cost calculation device and a storage medium for current markets.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method, device and storage medium for calculating power generation costs used in the day-ahead market. Background technique [0002] At present, the regulation and management agencies of various power plants (Guangdong Central Regulation, Guangzhou Central Regulation, Shenzhen Central Regulation, etc.) form the monthly total power generation plan or the annual total power generation plan of the regulation and management power plant according to the base power plan and the transaction power of various markets. Therefore, When it is developed to the day-ahead market, the total monthly power generation plan cannot meet the day-ahead market (that is, the power generation plan cannot be formulated according to the daily electricity consumption), resulting in low power generation efficiency of various power plants. The power generation cost is the monthly or annual total powe...

[0002] At present, the regulation and management agencies of various power plants (Guangdong Central Regulation, Guangzhou Central Regulation, Shenzhen Central Regulation, etc.) form the monthly total power generation plan or the annual total power generation plan of the regulation and management power plant according to the base power plan and the transaction power of various markets. Therefore, When it is developed to the day-ahead market, the total monthly power generation plan cannot meet the day-ahead market (that is, the power generation plan cannot be formulated according to the daily electricity consumption), resulting in low power generation efficiency of various power plants. Power generation cost Get the monthly or annual total power generation cost, that is, the product of the monthly total output of the unit and the average power generation cost

However, in the day-ahead market, the mid- to long-term power market (monthly total power generation plan or annual total power generation plan) changes daily because the coal consumption cost of power plants changes, so the calculation of the total power generation cost for the entire month based on the average power generation cost results in The calculated generation cost of the power plant has a large deviation
