Problems solved by technology

[0002] With the rapid development of the economy, the load of my country's power grid is increasing day by day. However, factors such as uneven distribution of land resources and difficulty in grid expansion work have led to insufficient power supply capacity of the power grid in some areas, which cannot meet people's growing living needs. Therefore, we are looking for The method to alleviate this contradiction is the primary task of today's power grid construction

Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0057] Such as figure 1 As shown, an optimal power flow calculation method includes the following steps:

[0058] Step 1. Based on the real-time parameters of the system and the operating principle of TCPST, establish a TCPST equivalent node injection power model without changing the original admittance matrix of the system; where the system is a system including TCPST;

[0059] Step 2, according to the TCPST equivalent node injection power model, establish the optimal power flow calculation model of the system considering the controllable phase shifter;

[0060] Step 3, solving the system optimal power flow calculation model to obtain the system optimal power flow.

[0061] The above method ...

Abstract

The invention discloses an optimal power flow calculation method and system, a storage medium and calculation equipment. According to the invention, a system optimal power flow calculation model considering a controllable phase shifter is established based on a TCPST equivalent node injection power model, and the system optimal power flow calculation model is solved to obtain system optimal power flow. Optimal power flow calculation of a power system containing TCPST is achieved, a basis is provided for formulating an optimal control strategy of the TCPST, and the safety and the stability of the power system are improved.

Description

technical field [0001] The invention relates to an optimal power flow calculation method, system, storage medium and calculation equipment, belonging to the field of power system analysis and calculation. Background technique [0002] With the rapid development of the economy, the load of my country's power grid is increasing day by day. However, factors such as uneven distribution of land resources and difficulty in grid expansion work have led to insufficient power supply capacity of the power grid in some areas, which cannot meet people's growing living needs. Therefore, we are looking for The method to alleviate this contradiction is the primary task of power grid construction today. [0003] As a new generation of flexible AC power transmission device, TCPST (including thyristor-controlled phase shifter) can realize flexible control of bus voltage and line power flow by adjusting the parameters of controllable components without changing the original grid structure of th...
