【摘要】：隨著智能電網的快速發(fā)展,各種類型的可調負載逐漸普及。相比于傳統意義的電網,智能電網可以進行負荷調度,維持電力系統的穩(wěn)定運行狀態(tài)。因此,如何有效地進行負荷調度控制、優(yōu)化負荷曲線、優(yōu)化電網內功率潮流等問題日益受到關注。本文基于智能電網的背景,開展關于可調負載的優(yōu)化調度方法及仿真研究,具體研究內容包括:(1)針對靜態(tài)控制系統,提出一種含供電約束的負荷優(yōu)化控制方法。根據系統特征對各類負荷進行建模,并考慮供電約束,通過建立有效的目標函數,將可調負荷調度問題轉化為可解決的優(yōu)化控制問題。利用分布式控制策略,實現負荷曲線的優(yōu)化。(2)針對實時分布式系統,提出一種含供電約束的可調負荷調度策略。該策略可對發(fā)電過程中的波動進行補償,實現負荷曲線對供電曲線中的實時追蹤。通過對相關變量進行預測,實現可調負載隨機接入電網,并引入虛擬負荷等概念,進而提出實時控制方法。(3)通過引入分支流模型,對配電網中的潮流優(yōu)化控制方法進行分析與研究。采取逐步松弛的策略,將原非凸的NP難題轉化為簡單問題,從而實現了分支流模型的求解。
[Abstract]:With the rapid development of smart grid, various types of adjustable loads are becoming more and more popular. Compared with the traditional power grid, smart grid can carry out load dispatching and maintain the stable operation state of power system. Therefore, how to control the load effectively, optimize the load curve and optimize the power flow in the power network has been paid more and more attention. In this paper, based on the background of smart grid, the optimal dispatching method and simulation research on adjustable load are carried out. The specific research contents include: 1) for static control system, a load optimal control method with power supply constraints is proposed. According to the characteristics of the system, the load scheduling problem is transformed into a resolvable optimal control problem by establishing an effective objective function and considering the power supply constraints. Based on the distributed control strategy, the load curve is optimized. (2) for the real-time distributed system, an adjustable load scheduling strategy with power supply constraints is proposed. This strategy can compensate the fluctuation in the process of generation and realize the real-time tracking of load curve to the power supply curve. By predicting the related variables, the adjustable load can be randomly connected to the power network, and the concept of virtual load is introduced, and then a real-time control method. The power flow optimization control method in distribution network is analyzed and studied. By adopting the strategy of gradual relaxation, the original non-convex NP problem is transformed into a simple problem, and the solution of the branching model is realized.
