| 摘 要： | PSASP_UPI可将PSASP和Simulink结合起来,弥补PSASP在光伏建模上的劣势,但PSASP在仿真时不会控制UP的仿真步长,导致其对Simulink模型利用不完全,甚至仿真结果失真。针对该问题,提出了一种基于改进UP的混合步长仿真方法。利用Simulink Code将光伏并网模型编译成C代码并嵌入UP中,在VC环境改进UP为每接收一次PSASP的计算结果就把它作为初值单步计算一百次,保存每次计算结果并将最后一次的计算结果传给下一时刻的PSASP。PSASP搭建的CEPRI 36节点光伏并网仿真算例表明改进UP的混合步长仿真的方法相对固定步长仿真方法更具精确性和可行性。

| Abstract: | PSASP_UPI can combine PSASP and Simulink to make up for the disadvantages of PSASP in PV modeling. However, PSASP cannot control the simulation step size of UP, which may resulting in incomplete utilization of Simulink model and even distortion. In view of the problem, a hybrid step size simulation method based on improved UP is proposed in this paper. The photovoltaic grid connected model is compiled into C code through Simulink Code and embedded to UP. The UP is improved in VC to calculate one hundred times step-by-step every time it receiving PSASP"s calculations at one time, saving each calculation result and passing the last calculation to the PSASP at the next time. The simulation example of CEPRI 36 nodes PV grid connected model built in PSASP shows that the improved UP hybrid step simulation method is more accurate and feasible compared with the fixed step size simulation method, |
