“…More and more renewable energy sources, such as solar and wind power, are being connected to the grid on a large scale, coupled with a gradual increase of new loads with uncertain characteristics, which results in the significantly enhanced uncertainty in the power system. The secure and stable operation of the power grid faces severe challenges [1, 2]. As one of the key parameters of power system, frequency is affected by various uncertain factors, and frequency security events related to uncertainty have occurred one after another.…”

In modern power systems, the impact of random power sources and loads on power systems is increasing, resulting in threatened system frequency security. However, traditional methods are often not comprehensive in modelling randomness, and there is no analytical method to assess the frequency response of power systems under uncertain power fluctuations. Here, the power fluctuation in a power system is regarded as an interval random quantity. An analytical prediction method of the power system frequency deviation under uncertain power fluctuation is proposed. Through further deduction, the allowable range of power fluctuation under the premise of secure frequency deviation can also be defined, which provides a reference for frequency security and accident prevention in power systems. Numerical simulations with the model of the East China Power Grid demonstrate that the proposed analytical method can delimit the response interval of system frequency deviation well, and the backstepping calculation can also delimit the allowable range of power fluctuation to ensure the secure operation of the system.
