The proportion of wind energy in global structure is growing rapidly, promoting the development power forecasting (WPF) technologies to solve uncertainty and intermittence generation. However, nonlinear stochastic features time series restrain accuracy multi-step prediction performance. A WPF (MS-WPF) approach based on a bi-level empirical mode decomposition (BLEMD) method BiLSTM neural network proposed this paper improve regional generators. Since always generated through coupled factors...
The applicability of a two-degree freedom (DOF) internal model-based voltage control (IMVC) scheme for DC Microgrids (DCMGs) with unknown external disturbances is explored in this paper. One the most challenging aspects DC/DC converters maintaining reference tracking under and measurement noise while load changes simultaneously. This paper develops framework to address these challenges by plug-and-play model controller voltage-source (VSCs) at primary level. effectiveness proposed evaluated...
For multibus wind power plants in microgrids, it is challenging to develop a reliable, effective, and robust harmonic suppression method for voltages currents of all buses. This paper proposes hierarchical control mitigate the buses grid-forming plants. The proposed effectively reduces terminal currents, PCC voltage, grid current. It achieves adaptive mitigation automatic current sharing between turbine units according rated capacity feeder impedance each unit. effectiveness verified planned...
A fuzzy logic based online energy management system (FLEMS) is designed in this paper to achieve the optimal electricity cost a residential Microgrid (MG). The proposed FLEMS combined by local price model (LEPM) and fuzzy-logic strategy. LEPM will preprocess sampling data estimate market MG status. mimics artificial intelligent assessment economic issues make decision for charging discharging operation storage (ESS). In FLEMS, not only supply-demand balance, but also ESS state of charge are...
For virtual synchronous generator (VSG) based microgrids, it is challenging to address the adverse effect of nonlinear loads and grid background harmonics with existing harmonic suppression methods. To this issue, a decomposed current (DHS) method proper feedforward point common coupling voltage feedback VSG output as well load proposed for VSG-based microgrids. The DHS can separately mitigate caused by harmonics, obtaining promising without potential system instability problem. Compared...
Power quality issues are challenging to deal with by conventional harmonic suppression methods in a virtual synchronous generator-based system connected the distorted grid. To address this issue, phase-compensated method is proposed effectively suppress grid current for generator The developed according Nyquist diagram improve control bandwidth and stability. With method, component suppressed, sensitivity distance of maximized, total distortion (THD) reduced from 8.53% 2.97%, response time...
The measurement and model errors always exist in the sample or data analysis part of Microgrids (MGs) system, bringing oscillation inaccuracy to controller energy management system (EMS). This paper proposed a Kalman filter (KF)-based control strategy for battery storage (BESS) MGs with integrated renewable sources. scheme aims at minimizing active reactive power purchased from main grid by regulating output current BESS. A detailed wind-PV-battery MG is built, sampling considered. tested...
