The consumption of renewable energy is driving the development of energy storage technology. Shared energy storage (SES) is proposed to solve the problem of low energy storage penetration rate and high energy storage cost. Therefore, it is necessary to study the profit distribution and scheduling optimization of SES. This study proposes a SES-Prosumers model, using chance constraint and robust optimization to cope with uncertainty in PV generation and electricity price, respectively. Then, the SES-Prosumers cooperative optimization model is established based on Nash negotiation theory. The original Nash negotiation problem is equivalently transformed into the SES-Prosumers system benefit maximization subproblem and the energy trading negotiation subproblem. Finally, the alternating directional multiplier method (ADMM) is used to solve these two subproblems in a distributed manner to protect the privacy of each participant. The simulation results show that the proposed strategy can effectively improve the operational benefits of each subject and its ability to deal with uncertain risks.

Under the background of double carbon strategy goal, the development prospect of wind power is very broad because of its advantages such as low cost and easy expansion. However, wind power output has strong random volatility, and large-scale wind turbine connected to the power grid through power electronic devices will not actively respond to changes in external frequency. The inertia stored in the rotor is difficult to provide inertia support for the system, resulting in a decline in the overall inertia level of the system, which further reduces the anti-disturbance ability and threatens the stability of the system frequency. In this paper, an online identification method of inertia of power system based on ARMAX model is proposed. The accuracy of this identification method is verified by comparing the inertia of motor and doubly-fed wind turbine under pulse disturbance and step disturbance. This method does not need to apply large disturbance and has higher security.

The characteristics of asymmetrical short-circuit current of doubly fed induction generators (DFIGs) are different from those of synchronous generators (SGs). With the increase in the quantity and capacity of DFIGs, the analysis and calculation of the asymmetrical short-circuit current of DFIGs are vitally important for the safe and stable operation of modern power systems. Under asymmetrical fault conditions, protection circuits and control strategies of DFIGs have multi-time scale characteristics and the equivalent circuit will change accordingly. Moreover, the negative-sequence internal voltage of DFIG is controllable, which makes the analysis more complex. This paper proposed an analytical calculation method of the asymmetrical short-circuit fault current and the characteristics of fault current are analyzed considering the multi-time scale control and protection. Finally, the proposed expression is validated in MATLAB/Simulink.

Under the continuous promotion of the "double carbon" strategic goal, the "oil to electricity" development momentum of heavy trucks is strong, and the pure electric heavy truck has become the main mode of logistics and transportation. Overall scheme design of aggregation regulation and control for friendly interaction between pure electric heavy truck cluster and power grid is proposed in this paper. Firstly, the aggregation regulation and control system are expounded from four dimensions of the problem solved, the technological innovation point, the deployment framework and the functional framework. Secondly, based on the perspective of power grid side, the comprehensive function and application scenario of the upper-level interactive control platform of pure electric heavy truck cluster is designed. Then, based on the perspective of aggregator side, the six functions of the middle-level aggregation management and control platform for pure electric heavy truck charging and changing station are constructed. Finally, based on the perspective of load side, the lower-level intelligent edge terminal of pure electric heavy truck charging and changing station is summarized, and the functional module is constructed from the three aspects of data processing, resource management and optimization control. The overall scheme of aggregation regulation and control designed in this paper is helpful to realize the friendly interaction between the pure electric heavy truck cluster and the power grid, and further improve the safe and stable operation of power grid.

In this paper, according to the structural characteristics of marine medium voltage AC circuit breaker, a finite element model is established and harmonic response analysis is carried out. The transverse, longitudinal and vertical resonant frequencies and resonant points are pointed out respectively. The vibration test results are consistent with the simulation results, and the problem of component damage occurs in the longitudinal direction. Then, the prototype is improved according to the simulation results. When the frequency of the improved prototype is 30 Hz, the peak acceleration at the resonance point is reduced from 60 m/s2 to 40 m/s2; At 57 Hz, the peak acceleration at the resonance point is reduced from 40 m/s2 to 30 m/s2. The improved prototype successfully passed the vibration test. The vibration analysis method effectively solves the problem that the anti-vibration design of medium voltage AC circuit breaker completely depends on the test results and needs to be improved repeatedly, which has guiding significance for the anti-vibration design of similar equipment.

Electric vehicles (EVs) with mobile energy storage characteristics are a class of flexible and high-quality demand-side resources. In order to solve the problem that the load of EV charging stations is difficult to be accurately predicted, this paper proposes a high-order Markov chain-based EV aggregation model. Firstly, the Poisson distribution is used to predict the charging start time of EVs to solve the external influencing factors in the subsequent modeling; then, the State-of-charge (SOC) state of EVs is discretized in two layers, the first layer can clearly define the charging and discharging state of each EV in the charging station by using fuzzy partition, and the second layer continues to subdivide each interval on the basis of fuzzy partition to realize the double layer discretization, which reduces the dimensionality of the state space and Finally, the results show that the proposed model can accurately predict the load of EVs in charging stations.

It is significant to select the black-start scheme of the isolated grid which accelerate the recovery of the grid and restore the important load in time. It needs to be divided into several partitions in the total black state. This paper proposes an isolated grid black-start scheme evaluation method based on DEA/TOPSIS, for the judgment matrix of DEA/AHP is 1and TOPSIS weight definition lacks objectivity which can not be completely evaluated. DEA model is used to obtain the objective weight coefficient of each evaluation index, which solves the problem of TOPSIS weight definition; At the same time, TOPSIS makes a comprehensive ordering of all evaluation methods to save computing time and operation difficulty and avoid the situation that the evaluation results can not be judged. New England 10-Machine 39-Bus System is used as an example to verify the effectiveness of the proposed algorithm.

Distributed photovoltaic is generally connected to the distribution network through grid-following inverter, which may cause a series of stability problems when the connection ratio is high. The dual-mode inverter with grid-following and grid-forming can ensure the stable access to the grid of distributed photovoltaic by mode switching. Nowadays, the research mainly focuses on the switching strategy of grid-following/islanding, and there is little research on how to choose the optimal switching scheme when the distributed photovoltaic is connected to multiple points. In this regard, this paper focuses on the distribution system with dual-mode inverter access, and proposes a mode switching strategy that integrates the stability margin and voltage deviation requirements of the system to improve the power quality and stable operation when the system parameters change. The simulation results verify the effectiveness of the proposed mode switching strategy.

In this paper, an optimization method of high voltage cable circulating current suppression based on short-circuit current guidance is proposed to solve the problem that the current method cannot take into account the circulating current suppression under normal working conditions and the current suppressor protection in case of single-phase short-circuit fault. Based on the theoretical model, the line is divided into current suppression branch and reserved branch, and the parameters of each branch current suppressor are set, and the electromagnetic simulation model of multiple operating conditions is established to compare and verify the performance characteristics of the modified line. The results show that the optimization method proposed in this paper can reduce the circulating current level of the line and improve the ability of the current suppressor to deal with the fault. It has the characteristics of low cost and high investment efficiency and can provide theoretical reference for the actual line application.
