Fast estimation method of renewable energy carrying capacity of power grid based on nadir frequency constraint
نویسندگان
چکیده
With more and renewable energy connected to the power system, system gradually presents characteristics of low inertia risk frequency instability becomes prominent. Therefore, nadir has become one limiting factors carrying capacity. In this paper, firstly, based on swing equation, dynamic response after loss was analysed. Secondly, quantitative analysis time with resources carried out, higher penetration rate k replacement a, is relative lower. Thirdly, fast estimation method capacity grid constraint proposed. Finally, taking a regional as an example, effectiveness proposed verified.
