New energy active power control method for power generation right transaction in electricity market environment

Abstract

The invention discloses a new energy active power control method for a power generation right transaction in an electricity market environment. The new energy active power control method comprises the steps of: regarding the tracking of real-time lower spinning reserve of a thermal power generating unit as a general objective of new energy control, and calculating new energy power generation indexes; establishing a control group model according to power generation right transaction components, wherein power generation priority of each control group conforms to the priority of the corresponding component electric quantity; initializing grouping according to the power generation right component with the highest priority in each new energy field stations; carrying out intergroup distribution on the new energy power generation indexes according to the priorities of the control groups; performing precise control on the new energy field stations in the control groups after considering section constraint conditions and actual power generation capacities of different levels; and counting currently participating transaction component electric quantity of each new energy field station in real time, and automatically switching the control groups to realize hierarchical control of the power generation right after the component electric quantity index is completed until all power generation right electric quantity is completed. The new energy active power control method is of great importance in motivating new energy power generation enterprises to participate in the power generation right transaction and enhancing the level of new energy consumption.

Description

technical field [0001] The invention relates to the technical field of automatic power generation control of electric power systems, in particular to a new energy active power control method for power generation right trading in an electric power market environment.
