摘要
为直观描述风光发电制氢合成氨(power-to-ammonia,P2A)系统的柔性负荷调节潜力,计及制氢、合成氨化工过程的负载调控特性,基于动态规划思想和计算几何理论,提出其多时段可调度域(multi-stage dispatchable region,MSDR)的刻画方法.所提方法将多时段间相互耦合的鲁棒约束变换为"氢缓冲罐贮量-合成氨产率"状态空间中的确定性多面体约束,使得对于可调度域内的任意系统状态,均存在满足完整调度过程安全约束的"制氢流量—氨产率爬坡速率"控制序列,从而实现P2A系统可调度能力的可视化.所提MSDR模型可进一步用于构造多时段鲁棒优化调度,在保证可行性的前提下优化P2A系统的经济收益.最后,基于内蒙古自治区某在建示范工程构造算例,验证所提方法的有效性.
Abstract
To intuitively describe the load flexibility of the wind and solar energy-based power-to-ammonia(P2A)system,considering the varying-load adjustment characteristics of the hydrogen production and ammonia synthesis processes,a describing method of the multi-stage dispatchable region(MSDR)is proposed based on the idea of dynamic programming and the computational geometry theory.The proposed method transforms the multi-stage robust constraints into deterministic state-space polyhedral constraints.For any state in the dispatchable region,a control sequence that satisfies the constraints in the subsequent process exists.Therefore,the dispatch ability of the P2A system is visualized.The proposed MSDR model can be further used for multi-stage robust scheduling to optimize the profitability of P2 A under the premise of scheduling feasibility.Finally,a case study based on a P2A demonstration project under construction in Inner Mongolia,China,verifies the proposed method.
