Abstract

The main challenges in designing the power reserve control (PRC) lie in the rapid estimation of the maximum available power (<inline-formula><tex-math notation="LaTeX">$P_\mathrm{avi}$</tex-math></inline-formula>) in real-time and effective drift avoidance under the condition of fast-changing irradiation. Conventional PRC strategies utilize direct measurement or curve-fitting-based estimation to determine the <inline-formula><tex-math notation="LaTeX">$P_\mathrm{avi}$</tex-math></inline-formula>, which shows obvious limitations, such as extra hardware, implementation complexity, and slow estimation speed. Meanwhile, the drifted reserved power (<inline-formula><tex-math notation="LaTeX">$\Delta P$</tex-math></inline-formula>) may deteriorate the dynamic response performance, bring high dc-link over-voltage risk, and affect the system operation stability due to the voltage-step-<inline-formula><tex-math notation="LaTeX">$\Delta P$</tex-math></inline-formula> regulation mechanism in conventional PRC methods. To address these issues, an improved PRC strategy with a fast <inline-formula><tex-math notation="LaTeX">$\Delta P$</tex-math></inline-formula> transient mechanism is proposed with the rapid estimation of <inline-formula><tex-math notation="LaTeX">$P_\mathrm{avi}$</tex-math></inline-formula> through just one pair of PV voltage and current sampling. Thus, the proposed algorithm is cost-effective, easy to implement, and compatible with existing PV systems since no additional hardware components are required. Moreover, the proposed PRC breaks through the inherent limitation of the voltage-step-<inline-formula><tex-math notation="LaTeX">$\Delta P$</tex-math></inline-formula> mechanism, which can ensure the <inline-formula><tex-math notation="LaTeX">$\Delta P$</tex-math></inline-formula> drift mitigation even under fast-changing weather conditions. Main experimental comparisons with other advanced PRC strategies were conducted to verify the advantages of the proposed algorithm in terms of rapid real-time available power estimation and drift avoidance.
