Trading volume locking and releasing design method for electric power market trading activity

The invention relates to a trading volume locking and releasing design method for an electric power market trading activity. The method includes the steps: (1) reporting trading; (2) checking effective power generation capacity; (3) locking trading volume; (4) releasing trading volume. The method mainly solves the technical problems that when a certain electric power market member takes part in various concurrence trades, trading contracts cannot be performed in a trading period as the electric power market member participates in too many trades, a main reason is that the power generation capacity of power generation enterprise market members is limited, and contract electric quantity exceeds a maximum value of the power generation capacity of the power generation enterprise market members. The trading capacity of the market members is automatically locked and released in a trading reporting period, the maximum power generation capacity of the power generation enterprise market members is checked, power generation enterprises are limited to participate the trades exceeding the range of the power generation capacity of the power generation enterprises, so that the power generation enterprises have the capacity of executing signed trading electric quantity contracts.
