The variable projection based Steffensen acceleration (VP-SA) algorithm is proposed for battery state of health estimation. The VP-SA algorithm exploits the separability of variables to reduce the dimensionality of the parameters, which can improve the estimation efficiency. In addition, based on the Steffensen acceleration method, the convergence rates of the VP algorithm can be increased. The simulation example shows the effectiveness of the proposed algorithm.

“…Battery SOC cannot be measured directly, but can only be estimated by parameters such as battery terminal voltage, charge/ discharge current, and internal resistance. [45][46][47] Remark Then, the SOC of the battery can be estimated based on the measured open-circuit voltage. The ampere-time integration method directly calculates the SOC value in real time by the definition of SOC.…”

With the popularity of lithium-ion batteries, battery state of health (SOH) estimation has become one of the current research hotspots. Due to network congestion, collected data usually encounter time-delay or packet loss. In this paper, an expectation maximization (EM) algorithm is proposed for the SOH model which is approximated by a polynomial model. Based on the EM method, the missing data are computed in the E step, and the parameters are updated in the M step. Compared with the least square method, the proposed algorithm has more accurate estimation accuracy. The simulation example shows the effectiveness of the proposed algorithm.

“…For this purpose, the sagging control strategy was introduced in references [72,73] to improve the unbalanced distribution of multi-storage power. Reference [74] proposed a new droop control strategy for DC microgrids to ensure that distributed energy storage and power distribution of adaptive regulatory load can be coordinated under normal communication and no communication conditions. The control strategy can be smoothly switched under the two working conditions, and the distributed energy storage SOC balance and load power dynamic distribution (coordination and distribution between multiple energy storage) can be realized.…”

With the continuous development of new energy generation technology and the increasingly complex power grid environment, the traditional black start scheme cannot meet the requirements of today's power grid in order to ensure the stable operation of the power system can be restored quickly in the face of large power outages, so a more complete black start scheme needs to be developed to cope with the new power system. With the development of energy storage technology, the limitations of the traditional black-start scheme can be solved by new energy farms with energy storage configuration. Therefore, this paper investigates the problems faced by black-start, the key technologies of energy storage assisted new energy black-start, and introduces the research related to new energy black-start technology to provide reference for future research and application of new energy black-start.
