高維模型表達在概率潮流和靜態(tài)安全域中的應(yīng)用研究
[Abstract]:In recent years, with the continuous expansion of power system scale and the emergence of more and more uncertain factors in power network, probabilistic power flow and static security region are two important tools for power system security assessment and regulation. It has attracted more and more attention. Seeking simple and efficient methods in the application of probabilistic power flow and static security domain has become a hot topic in engineering research. High-dimensional model representation (High Dimensional Model Representation,HDMR) has a unique performance in describing the relationship between system output and multiple inputs, while the power flow state and the injection of multiple nodes in the network are exactly in line with the correlation attributes of HDMR. On the basis of analyzing the principle and modeling process of HDMR model, this paper uses the information of source and stream path chain to find the load and generator node that affect the key branch power flow, and uses the developed GUI-HDMR program to model the HDMR model of branch power flow. The model is modified by modifying the order of input quantity and the degree of orthogonal polynomial, and the complex power flow equation is replaced by simple polynomial combination. In order to avoid large-scale model reconstruction, the HDMR model of branch power flow is modified with sensitivity compensation method in this paper, which saves a lot of time. The IEEE39 node example shows that the HDMR model can fit the power flow equation well and can be used to calculate the power flow state quickly. In this paper, HDMR is applied to power flow probabilistic evaluation and control problem: the HDMR relation between power transmission and power supply and load is constructed through typical representative samples. In order to improve the efficiency of generating the cumulative probability distribution of critical branch power flow and its related characteristics, the traditional power flow calculation method is used to take on the task of large-scale power flow calculation in the process of power flow probabilistic evaluation. A probabilistic control strategy based on the global sensitivity information provided by HDMR and taking into account the performance index of energy saving and emission reduction is designed. An example shows that the application of HDMR can significantly improve the efficiency of power flow probability evaluation and the performance of power flow blocking probability control in key branches. In order to solve the problem that the calculation of AC power flow model is heavy and the accuracy of DC power flow equation is not high during the calculation of static safe domain, this paper uses HDMR model to replace AC or DC power flow equation in static safe domain, which not only guarantees the calculation speed. Moreover, the accuracy of calculation is improved. Under the condition that the range of active power of some generators is known, a new method to calculate the security region of the power variation of the node subset is proposed. An example shows that the application of HDMR can significantly improve the efficiency of static security domain construction.
