Introducing energy storage units in wind and photovoltaic systems can smooth output power and enhance system schedulability. These schedulable new energy resources can provide frequency and voltage support under VSG control strategy, thereby enhancing the stability and reliability of the power system.
Through in-depth analysis of the output characteristics and dynamic behavior of new energy, the fast and stable response of new energy power systems in the large-scale fluctuations can be achieved. It is hope to enhance frequency stability based on the adaptive adjustment ability of the enhanced system.
The model includes new energy generation, energy storage system, and VSG control module to simulate load fluctuations and their impact on frequency response. The initial state of charge of the energy storage system is set to 50%, taking into account the frequency changes and response characteristics under different operating conditions.
The PV is participated in frequency regulation by modifying the modulation index in response to the frequency deviation. In a 1.2 kW PV system the proposed scheme was validated where only 3% of the PV output is modulated. Fig. 16 shows the control block of the modulated PV system, where the ramp rate limiter controls the PV output within 50 W/min.
From the results, the damping of the system increased, the oscillation frequency decreased after a duration of about 15 s, and the system stability improved by 76.09%. The proposed strategy based on virtual synchronous generator adaptive energy storage coordination control strategy was improved by 83.25%.
A novel improved frequency stabilization approach based on modified fractional order tilt controller is presented for interconnected diverse power systems with integration of sea wave energy, photovoltaic, wind, energy storage system and biodiesel generator.
