Embodiment Construction

[0092] Coordinated dispatching of the power system is to integrate the cooperation between active loads and renewable energy generation throughout the entire operation of the power system, which requires the organic coordination of decision-making at different time scales such as day-ahead time level, advanced time level, and real-time time level. Among them, the coordinated advance scheduling decision is the link between the day-ahead scheduling and AGC control, and the relationship with other time-scale decisions must be considered to ensure the effectiveness of the decision-making results. To this end, the relevance of cooperative lookahead scheduling to other timescale decisions is illustrated.

[0093] Such as figure 1 As shown, the coordinated advance dispatch plays a connecting role in the coordinated dispatch, and its decision-making will be directly affected by the decision-making results of unit combination and the implementation process of AGC control.

Abstract

The invention relates to an establishment method of a collaborative power grid advanced scheduling model. The establishment method comprises steps that 1), the related power grid parameter information, the current scheduling decision result information, the super short period load prediction result information and the wind power prediction result information are acquired; 2), minimizing AGC set operation cost and renewable energy power generation is taken as a target, in combination with operation constraint conditions and relevance with current scheduling and an AGC control process, the collaborative power grid advanced scheduling model is established, and an expression described in the specification is acquired. The invention further comprises a calculation method of the collaborative power grid advanced scheduling model. Through the establishment method, an active load adjusting speed advantage is fully performed, cooperation of active loads and renewable energy power generation during current scheduling is further refined, and power grid consumption renewable energy power generation capability is improved.

Description

technical field [0001] The invention relates to the technical field of power system operation and control, in particular to a method for establishing a coordinated power grid advanced dispatching model and a calculation method thereof. Background technique [0002] Advance scheduling, also known as online scheduling, is the link between day-ahead scheduling and automatic generation control (AGC), and its results will directly determine whether AGC can achieve the expected results. [0003] With the large-scale grid integration of renewable energy such as wind power and photovoltaics, the uncertainty faced by advanced scheduling has increased. In this regard, some studies have proposed the concept of the allowable operating range of renewable energy power generation, and established a robust scheduling model targeting the maximum range; some scholars have also proposed to establish an advanced scheduling model based on adjustable robust optimization, through the establishment...
