Recent years, modular multilevel converter (MMC) is one of the most promising topologies applied to high voltage direct current transmission (HVDC). In order to solve the circulating currents caused by structural defects of MMC, a fuzzy adaptive PI circulating current suppressing controller is proposed based on mathematical model of MMC and functioning fuzzy subset inference method: The fuzzy number is calculated according to the error of system state, error variation, membership function and fuzzy control rules; The center of gravity method is used for defuzzification, and finally the PI parameters are modified. Finally, the PSCAD/EMTDC simulation model with fuzzy adaptive PI controller is established. The results show that the fuzzy adaptive PI circulating current suppressing controller is effective for MMC-HVDC.

Real-time assessment of the risk of continuous commutation failure of the thyristor-based phase-controlled commutation direct current transmission system (LCC-HVDC) and timely preventive control measures are of great significance to ensure the safe and stable operation of the large power grid. This paper proposes a method for evaluating effective dynamic reactive power reserve of generators to deal with DC continuous commutation failure. The maximum reactive power increment of the generator corresponding to the secondary drop of the converter bus voltage is defined as the effective dynamic reactive power reserve. The effective dynamic reactive power reserve at the critical point is called the maximum effective dynamic reactive power reserve. When the system dynamic reactive power reserve is less than the reserve capacity threshold, a two-stage preventive control measure searching method is adopted. First, increase the terminal voltage of the generator and the static reactive power compensation. If the requirements are still not met, the start-up unit measures will be adopted. An example of an actual power grid verifies the effectiveness of the method. © 2021 IEEE.

Nowadays as quantities of renewable energy resources are integrated to the power grid, their fluctuation and uncertainties influence violently to power system operation. Stochastic power flow is utilized to handle this issue. However, conventional stochastic power flow did not consider correlation in renewable energies, especially wind farms, leading to errors in power flow analysis. To address this problem, this paper proposes a linear correlation clustering method, which decomposes the non-linear correlated wind power data to several linear models to solve. The data generated from the nonlinear probabilistic distribution is clustered according to similar linear property, still keeping their major features and characteristics. Through analysis in a case study, it is proved that the proposed linear correlation clustering method performs better than existing Gaussian mixture model in both accuracy and computational efficiency. It is insightful to be utilized for stochastic power flow calculation in power system planning and operation. © 2017 IEEE.

Wind power has the characteristics of randomness and intermittent, with the increasing unit capacity of wind turbines and wind farm scale, it is urgent to study the impact on generation and transmission system reliability. In addition, there are different degrees of correlation among regional multiple wind farms because of their geographic proximity. When it comes to research on the influence on the power system reliability, the analysis result will be larger error without considering the correlation, which is optimistic for reliability assessment. Therefore, it is meaningful to take the correlation into account in wind power system reliability assessment. In this paper, IEEE-RTS 79 generation and transmission reliability test system is adopted to verify the reliability assessment of power systems with wind farms considering correlations. The experimental results show that adding wind turbines in the original power system, system reliability has been greatly improved;and the system has higher reliability with given the considering the correlation between wind farms. © 2021 IEEE.

Failure of the DC system itself to withdraw from operation or failure of the AC system causing blocking of the DC system may result in a tidal shift to overload the AC line. Unreasonable tripping of the AC line's distance III backup protection based on local information drives the development of chain tripping incidents and can lead to significant outages. For this reason, a method based on conservation and control synergy is proposed, using DC control information to optimise AC distance III backup protection action behaviour. When the tidal shift triggered by the DC phase change failure blocking makes the distance protection section III act unreasonably, the DC control information is used as the activation condition for the backup protection action range adjustment to improve reliability and prevent the backup protection from acting unreasonably. Finally, the effectiveness of the above strategy is verified by PSCAD software simulation. © 2022 IEEE.

The power system becomes more complex, due to the high penetration of renewable energy and more electronic devices are integrated to the traditional grid. SSCS is the critical task for power grid operation to ensure the control reliability and effectivity. It is inevitable to improve verification experiment technology for SSCS considering the development trend of the power system. RTDS is a powerful simulator for power system which is able to reflects the practical power system operation in real time. In this paper, a method for status tracking of power system model in RTDS is developed that SSCS is able to be verified under multiple operation conditions. It is found that the status cannot be tracked consistently as given, due to the limitations of RTDS models and raw data. The limitation in tracking reactive power output of generators is overcame in this paper. Besides, the development trend of online stability analysis and control is discussed as well as SSCS verification experiment technology. © 2021 IEEE.

Safety is an important factor restricting the cascade utilization of lithium-ion batteries (LIBs). In this paper, the safety characteristics of fresh and retired lithium iron phosphate batteries are investigated by means of a heating-triggered thermal runaway (TR). The results show that under the heating condition of 200 W, the internal short circuit (ISC) can directly cause the TR of a new battery and lead to an explosion with an overpressure of 98.9 kPa. However, there is still a buffer time of 13.1-22.3 min between the ISC and TR for the retired battery with states of health (SOHs) of 80% - 60%, and the retired battery cannot explode. The large-scale ISC onset time, TR onset time, and TR onset temperature of the 70% SOH battery are 27.4 min, 40.5 min, and 179.9 °C, respectively, which are the smallest among retired batteries, indicating that the 70% SOH battery may be more likely to trigger TR. The findings can provide guidance for the safe application of retired batteries. © Published under licence by IOP Publishing Ltd.
