摘要:

基于多目标分层优化求解方法,兼顾系统平衡与调度经济性,构建海上能源岛多能互补系统分层协同优化模型。为应对风电与光伏出力的波动性与随机性对系统调度的影响,采用随机模型预测控制(SMPC)方法对海上能源岛系统调度进行优化求解。提出一种自适应变步长SMPC的调度方法,该方法在SMPC滚动优化环节,通过偏差参考系数追踪实时的调度偏差程度并据此动态调整滚动优化步长,解决了传统SMPC调度方法在滚动优化环节存在的调度精度缺失与易陷入局部优化的问题,兼顾了调度的精确性与全局性。仿真结果表明,该方法可有效提升调度精度,缩短计算时间。

Abstract:

Based on a multi-objective hierarchical optimization method, a hierarchical collaborative optimization model for the multi-energy complementary system in an offshore energy island was constructed, considering both system balance and economic efficiency of scheduling. To address the impact of the volatility and randomness of wind and solar energy on the scheduling of the offshore energy island system, the stochastic model predictive control (SMPC) method was adopted to optimize the scheduling of the offshore energy island. A scheduling method of adaptive variable step-size SMPC was proposed. In the rolling optimization link of SMPC, the real-time scheduling deviation degree was tracked through a deviation reference coefficient using the proposed method, and the rolling optimization step-size was adjusted accordingly. This addressed the problems of scheduling accuracy loss and local optimization in the rolling optimization phase of the traditional SMPC scheduling method, thereby balancing scheduling accuracy and globality. The simulation results show that this method can effectively improve the scheduling accuracy and shorten calculation time.
