摘　　要：智能配电网中,LED灯具有发光光效高、使用寿命长等优点,得到迅速推广和应用。基于LED灯独特的光电特性,研究大量LED灯接入分布式发电系统对电力系统的影响,建立LED灯参与分布式发电系统优化调度的数学模型。为了解决该数学模型,采用梯度投影法,并进行SIMULINK仿真,仿真结果表明,该算法收敛速度快、计算精度高,验证了算法的正确性和可行性。Owing to the advantages of high luminous efficiency and long lifetime, LED lamps get rapid promotion and application in the smart distribution network. Based on the optical and electrical unique properties of LED lamps, the authors studied the effects on the power system for a large number of LED lamps connecting to the distributed generation system, and establishing the mathematical model of LED lamp participating in the optimal dispatch of distributed generation system. The gradient projection method was applied to solve the model. SIMULINK simulation was carried out, results demonstrated that the algorithm had a fast convergence speed and high precision, and verified the correctness and feasibility of the algorithm.
