【摘要】：具有能量存儲特性的負(fù)荷主動參與功率平衡控制,將對系統(tǒng)運(yùn)行帶來積極影響。以空調(diào)負(fù)荷為例,設(shè)計(jì)一種負(fù)荷調(diào)度控制構(gòu)架,提出基于多樣性保持的負(fù)荷群調(diào)度控制策略。首先,分析負(fù)荷控制造成負(fù)荷群多樣性破壞的機(jī)理,提出保持多樣性的控制策略,考慮通信延遲對控制效果的影響,根據(jù)隨機(jī)抽樣理論設(shè)計(jì)負(fù)荷群跟蹤有功控制指令的算法。為避免負(fù)荷恢復(fù)時(shí)出現(xiàn)"二次峰荷",提出分時(shí)段負(fù)荷恢復(fù)策略。之后,在卡爾曼濾波估計(jì)負(fù)荷群運(yùn)行狀態(tài)的基礎(chǔ)上,建立負(fù)荷群的優(yōu)化調(diào)度模型,采用混合整數(shù)規(guī)劃法進(jìn)行求解。最后,通過算例仿真驗(yàn)證了所提空調(diào)負(fù)荷群調(diào)度控制策略的有效性。
[Abstract]:The active participation of load with energy storage in power balance control will have a positive impact on the operation of the system. Taking air conditioning load as an example, a load dispatching control framework is designed, and a load group scheduling strategy based on diversity maintenance is proposed. Firstly, the mechanism of load group diversity destruction caused by load control is analyzed, and a control strategy to maintain diversity is proposed. Considering the influence of communication delay on control effect, an algorithm of load group tracking active power control instruction is designed according to random sampling theory. In order to avoid the "secondary peak load" in the recovery of load, the strategy of load recovery is put forward. Then, on the basis of Kalman filter to estimate the running state of load group, the optimal scheduling model of load group is established, and the mixed integer programming method is used to solve the problem. Finally, the simulation results show the effectiveness of the proposed control strategy.
