“…Cheng et al 26 designed a modified distributed Kalman filter (KF) based on the mixed phasor measurement unit (PMU) and RTU measurement model that independently estimated local states via local measurements. Munsi et al 27 proposed the use of an algorithm based on the unscented Kalman filter (UKF) to control the voltage and current of a microgrid against unknown noise. Che and Shahidehpour 28 investigated the power flow between a DC microgrid and a main grid from the perspectives of economy, optimization and stability and designed a three-level control strategy for a DC microgrid.…”

“…In ( 6), the measurement functions h k (•) typically represent the standard real and reactive power observation of node power injection or line power flow. With the advancement of PMU technology, direct measuring states of voltage magnitude and phase angle are also possible [27], [28]. However, the extensive collection of real-time observations may not only raise meter installation costs but also lead to filtering information redundancy.…”

“…The efficiency and robustness of nonlinear and linear power flow model-based FASE estimators are included in comparisons under different simulation scenarios. Different state forecasting and filtering configurations for the six estimators are shown in Table I, where |V | and θ represents the measurement of voltage magnitude and phase angle; nonlinear PJ and PF represents the nonlinear measurement equations of power injection and power flow in filtering stage (i.e., extended Kalman filter, EKF [28]). For EKF-FASE-II and DC-FASE-II, the full system state derivation on the nonlinear PJ and DC PJ equations are implemented as the state transition model in forecasting stage.…”

“…The well group production used DC bus power supply components to form a small DC microgrid, which incorporated several new energy sources such as wind power, photovoltaic power generation and network electricity to form a distributed multi-source DC microgrid. The DC microgrid connects the control cabinets of multiple pumping units in parallel through the DC bus, and the integrated inverter and Remote Terminal Unit (RTU) in the control cabinet can realize the mutual feed-sharing and recycling of the power generated by multiple pumping units [12][13][14][15]. The multi-source DC microgrid has commonness and mutual influence among each other [16][17][18][19].…”
