Abstract
- This article developed a new methodology of macro dynamic demand response (DDR) strategy considering micropower quality disturbance (PQD) for wind-storage integrated systems. A novel idea has been presented in this methodology to eliminate the barrier of PQD and renewable energy dynamic adjustment. At the microlevel for PQD elimination, a filtering strategy of Butterworth–Wiener filter (Bw-WF) is proposed to deal with the frequency interference PQD in wind-storage integrated system by Bw and the WF. The method connects the macro DDR and the PQD elimination at the microlevel for the stable wind power output after PQD elimination. At the macrolevel for dynamic adjustment, the Hampel–Savitzky–Golay macropower filtering method is proposed to calculate the low-frequency power in line with the national standards. Considering all wind power participates in the DDR, the change of DDR and the adjusted power curves are calculated based on the Logistics function, optimistic response, and pessimistic response factors. Through the experimental verification, it is found that the power and state of charge curves of energy storage can be significantly changed by the subtle dynamic changes during an ultra-short period. Also, it is demonstrated that the theoretical method proposed in this article is reliable and promising.
