摘要

本文在考虑系统约束和发电机组约束的情况下，研究了与发电调度相关的光伏发电系统允许穿透量。采用混合整数二次规划(MIQP)方法求解机组承诺问题。高光伏渗透率降低了白天的净负荷。光伏发电在电网中的渗透率越高，净负荷曲线就越小。当光伏渗透率过大时，由于部分时段的净负荷爬坡高于发电机组的最大爬坡能力，算法无法找到机组承诺解。在光伏发电渗透率为69%时，由于发电机组爬坡不足，机组承诺问题无法解决。

Determination of Maximum Grid-Connected Photovoltaic Penetration Level Based on Unit Commitment Solution

This paper presents a study of the permissible photovoltaic (PV) power penetration related to generation scheduling by considering system and generator units constraints. The unit commitment problem is solved using Mixed Integer Quadratic Programming (MIQP). High PV penetration lowered net-load profile during the daytime. More PV penetration on the grid, the smaller the net-load profile occurs. When PV penetration is too large, the algorithm fail to find a unit commitment solution due to the net-load ramping at certain hours is higher than the maximum ramping capability of the generator unit. The infeasible solution of unit commitment problem occurred at PV penetration 69% due to the lack of ramp-up of generators.
