摘要: 为了在已投产的风光耦合发电站中实现制氢、储氢及燃料电池的最佳容量配比以及系统内部跟踪日前发电计划的优化调度,采用快速非支配排序遗传算法(NSGA-Ⅱ)实现了对容量配比多目标优化问题的求解,构建了考虑运氢量的风光氢发电系统内部跟踪日前发电计划的优化调度算法。首先,建立了各子系统的等效数学模型,提出了结合系统收益和全寿命周期年均值成本的经济性指标,以系统弃风弃光率、功率缺额率和经济性为目标得出制氢、燃料电池功率和储氢容量;其次,利用优化后的容量作为日前优化调度的约束条件,采用加权系数法建立了以日累计跟踪计划误差最小和储氢压力波动最小的单目标数学优化模型,利用Yalmip求解器对模型进行了求解;最后在Matlab中对所建立的模型进行了仿真和验证,得到了系统的最优容量配比,实现了系统内部跟踪日前发电计划的优化调度。

Abstract: In order to realize the optimal capacity allocation and day-ahead scheduling in wind-solar-hydrogen coupled generation system, the NSGA-II intelligent optimization algorithm is used to solve the multi-objective optimization problem of capacity allocation, and the optimal dispatching algorithm considering hydrogen transportation constraint is constructed on power generation side. Firstly, the equivalent mathematic model of each subsystem is established, and the economic indicator combining income and annual average cost of whole life cycle is put forward. Hydrogen production, fuel cell power and hydrogen storage capacity are obtained with the objective functions defined as system abandonment rate, power shortage rate and economy. Secondly, by taking the optimized capacity as the constraint condition of the day-ahead optimal coordinated control model, a single-objective optimization model is established to minimize the planning deviation and variation of pressure of hydrogen storage on the basis of the weighted coefficient method. Finally, the model is simulated and validated in Matlab. Hence the optimal capacity ratio and coordinated optimal control of the system is fulfilled.
