【摘要】：在对风水互补微电网的功率波动节能控制数学建模方法的研究过程中,采用当前的算法进行建模时受到大量的外界因素干扰,存在功率波动节能控制效果不佳的问题。为此,提出了一种基于功率曲线算法的风水互补微电网的功率波动节能控制数学建模方法。该方法针对运行的风水互补微电网系统进行分析,先计算出系统在不同自然条件下所需要的发电最大功率,依据系统在不同条件下对功率的需求设置2条或多条发电机机外特性曲线,在此基础上将风水互补微电网的功率波动节能控制问题转换为发电机与其功率平衡控制的问题,在保证负荷需求的基础上,以最大化利用风能和水能为原则,以整个系统的运行发电成本最低为目标建立风水互补微电网的功率波动节能控制数学模型。实验仿真证明,基于功率曲线算法的风水互补微电网的功率波动节能控制数学建模方法建模精确度高,鲁棒性强。
[Abstract]:In the process of studying the mathematical modeling method of power fluctuation and energy saving control in the geomantic complementary microgrid, the current algorithm is disturbed by a large number of external factors, and there is a problem that the effect of energy saving control of power fluctuation is not good. For this reason, a mathematical modeling method for power fluctuation and energy saving control of geomantic complementary microgrid based on power curve algorithm is proposed. This method is based on the analysis of the running geomantic complementary microgrid system. The maximum power of the system is calculated under different natural conditions. According to the power demand of the system under different conditions, two or more external characteristic curves of generator are set up. On this basis, the power fluctuation and energy saving control problem of the geomantic complementary microgrid is transformed into the control of generator and its power balance. On the basis of ensuring the load demand, taking the maximum use of wind and water energy as the principle, taking the lowest operating cost of the whole system as the goal, the mathematical model of power fluctuation and energy saving control of the geomantic complementary micro-grid is established. The simulation results show that the modeling method of power fluctuation and energy saving control based on power curve algorithm is highly accurate and robust.
