“…Power frequency modulation is a kind of auxiliary service with the demand of power generation enterprises for fast frequency modulation capacity as the trading object. Its purpose is to reserve a certain fast adjustment capacity of power generation enterprises to meet the needs of power generation and power deviation adjustment during the real-time operation of power grid [2][3]. In recent years, our country accelerated pushing forward the electric power structural reform.…”

In order to adapt to the demand analysis of power grid frequency modulation capacity under the rapid development of new energy and serve the construction of power frequency modulation market, a new power frequency modulation capacity demand assessment method considering the fluctuation of new energy is proposed. The purpose of reserving power frequency modulation capacity is to smooth the power generation deviation during the real-time operation of the power grid and keep the power grid frequency stable. At present, the deviation of power generation and consumption is mainly caused by the fluctuation of power load and the fluctuation of new energy output. Based on the analysis of the volatility of new energy and load, this paper proposes a method of power frequency modulation capacity demand assessment based on the volatility assessment. In this method, new energy and load fluctuation are regarded as independent variables, and the demand of power frequency modulation capacity is determined with the goal of maximizing the fluctuation of power generation and consumption. Finally, an example is given to verify the effectiveness of the proposed method based on the actual grid data of a province. The calculation results show that the evaluation results obtained by this method increase by 12.5% compared with the traditional method, which is more in line with the power grid operation requirements under the large-scale development of new energy.

“…Some studies have taken into account the problem of SOC management in the process of energy storage participating in FM. In reference [13], the control strategy of energy storage white adaptive frequency modulation and self-recovery is expounded by using the smoothing characteristic of logistic regression function. Although the SOC of energy storage battery is considered in reference [14], the regulation strategy of fixed power output participating in power grid frequency is still adopted.…”

In order to efficiently use energy storage resources while meeting the power grid primary frequency modulation requirements, an adaptive droop coefficient and SOC balance-based primary frequency modulation control strategy for energy storage is proposed. Taking the SOC of energy storage battery as the control quantity, the depth of energy storage output is adaptively adjusted to prevent the saturation or exhaustion of energy storage SOC. The balanced control strategy is introduced to realize the rational utilization of resources and the fast balance of SOC in the process of primary frequency modulation of energy storage battery under different charge states. Then, four evaluation indexes are proposed to evaluate the effect of primary frequency modulation and SOC maintenance. Taking a regional power grid as an example, a simulation analysis is carried out under step load disturbance and continuous load disturbance. According to the simulation results, the proposed control strategy is effective in power system frequency regulation and battery SOC maintenance.
