Description

Continuous and discrete reactive power source coordination control method based on dynamic coordination boundary threshold
Technical Field
The invention relates to the technical field of operation and control of power systems, in particular to a continuous and discrete reactive power source coordination control method based on a dynamic coordination boundary threshold.
Background
The secondary voltage control realizes the coordination calculation of various reactive power sources and control targets in the area, and is the core function of automatic voltage control. In the traditional two-stage voltage control, a two-stage method is adopted to solve the problem of mixed integer programming of discrete quantity and continuous quantity. The method can resolve the problems of discrete quantity and continuous quantity, and has good control convergence. However, the algorithm gives the control adjustment quantity of each reactive power source only according to a theoretical algorithm, the control cost of discrete and continuous reactive power sources is not considered, the discrete quantity switch has the control frequency limit within a certain time limit due to the physical characteristics of the discrete quantity switch, and the discrete quantity switch needs to be overhauled and replaced when the control frequency exceeds the control frequency; and the continuous quantity is adjusted through a unit excitation system, SVG or a fan and the like, and the control cost is far lower than the discrete quantity control cost. The traditional secondary voltage control does not consider the problems in the actual projects, and the phenomenon that the discrete quantity is excessively adjusted to cause the times to be out of limit or the switch equipment is rapidly aged can often occur, so that the occurrence of failure accidents of the switch and the control cannot be realized, and great hidden dangers are brought to the safe operation of a power grid.
Disclosure of Invention
The invention aims to solve the problem that the control cost of discrete and continuous reactive power sources is not considered in the traditional voltage control, and the problem that the number of times is out of limit due to discrete quantity over-regulation or the problem that the switch equipment is aged rapidly to bring great hidden trouble to the safe operation of a power grid often occurs.
In order to achieve the above object, the present invention adopts the following technical solutions:
the continuous and discrete reactive power source coordination control method based on the dynamic coordination boundary threshold is characterized by comprising the following steps of:
1) respectively calculating boundary threshold influence factors of a regional central bus and a substation monitoring bus;
2) calculating a dynamic coordination boundary threshold value of the regional central bus and the transformer substation monitoring bus according to the boundary threshold value influence factors of the regional central bus and the transformer substation monitoring bus obtained in the step 1);
3) adjusting the voltage limit ranges of the regional central bus and the substation monitoring bus according to the dynamic coordination boundary threshold values of the regional central bus and the substation monitoring bus obtained in the step 2), and obtaining the corrected voltage limit ranges of the regional central bus and the substation monitoring bus;
4) substituting the voltage limit ranges of the regional central bus and the substation monitoring bus corrected in the step 3) into the secondary voltage control model of the continuous quantity, correcting and solving the regional secondary voltage control models of the discrete quantity and the continuous quantity through a two-stage method.
The invention achieves the following beneficial effects: on the basis of the traditional two-level voltage control theory, the dynamic coordination boundary threshold value based on voltage constraint and reactive power source reactive power reserve is added to the central bus and the substation monitoring bus during continuous quantity adjustment, the voltage limit value interval is narrowed for adjustment, and the continuous quantity is pre-adjusted under the voltage constraint and the reactive power reserve constraint in a mode of changing the voltage limit value. Due to the fact that constraint of a bus voltage limit value and reactive reserve of a continuous reactive power source are considered, when the voltage is close to the limit or the reactive upper and lower reserve is insufficient, a coordination boundary threshold value is close to 0 and tends to coincide with a discrete quantity control limit value, and when load change or power grid disturbance is large, discrete quantity control can be triggered when the voltage exceeds the limit. The method effectively coordinates the coordination control problem of the continuous and discrete reactive power sources in the region by adjusting the coordination boundary threshold value of the central bus of the region, has very quick calculation speed, basically accords with the convergence with the traditional secondary voltage control, effectively reduces the adjustment cost of the discrete reactive power source of the power grid, and ensures the safe and economic operation of the reactive voltage of the power grid.
