In view of the need for stability analysis of large- scale new energy cluster connecting to large-scale power grid system, the existing electromagnetic transient simulation tools have certain limitations. At present, there is a lack of simulation platform that can uniformly establish large-scale new energy and large-scale power grid models. Based on two different simulation tools, RTLAB and CloudPSS, a large-scale new energy cluster and large-scale power grid electromagnetic transient co- simulation platform is built. A new energy station equivalence method based on single machine representation method is proposed, and the accuracy of the equivalence method is verified by comparing with detailed station model, which provides a basis for the modeling of large-scale new energy clusters. On the other hand, the electromechanical - electromagnetic model conversion tool based on CloudPSS is introduced, which provides a method for large-scale power grid modeling. At last, the decoupling principle and hardware implementation scheme of co-simulation model based on RTLAB and cloudPSS are presented and the comparison of simulation results verifies the accuracy of the simulation platform. © 2023 IEEE.

This work presents a pre-control approach based on wake propagation prediction to reduce the convergence time of the gradient-based wind farm maximum power point tracking (MPPT) distributed control method. Firstly, the proposed method modifies the control parameter before the wake affects the turbines downwind, which improve the convergence speed of the wind farm MPPT control. Secondly, a dynamic grouping method is given to build communication links between neighboring turbines, which makes the proposed method can be applied to an established wind farm. Finally, the control performance is validated by simulation results. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Currently, the power electronics-based devices, includinglarge-scale non-synchronized generators and reactivepower compensators, are widely used in power grids. This helpsintroduce the coupling interactions between the devices andthe power grid, resulting in a new sub-synchronous oscillationphenomenon. It is a critical element for the stability operation ofthe power grid and its devices. In this paper, the sub-synchronousoscillation phenomenon of the power grid connected with largescalewind power generation is analyzed in detail. Then, inorder to damp the sub-synchronous oscillation, a coordinateddamping optimization control strategy for wind power generatorsand their reactive power compensators is proposed. The proposedcoordinated control strategy tracks the sub-synchronousoscillation current signal to correct the corresponding controlsignal, which increases the damping of power electronics. Theresponse characteristics of the proposed control strategy areanalyzed, and a self-optimization parameter tuning method basedon sensitivity analysis is proposed. The simulation results validatethe effectiveness and the availability of the proposed controlstrategy.

Aiming at the GW large-scale power grid system with electrochemical energy storage and compressed air energy storage, a capacity allocation method of GW electrochemical energy storage power station based on time series production simulation is proposed. The wind and light output of 8760 hours is simulated by Markov chain analysis method, and then the mathematical model of hybrid energy storage and the economic optimal objective function are established, and the improved particle swarm optimization algorithm is used to solve the optimization. Finally, the model is simulated and calculated by the new energy production simulation software (REPS), and the optimal configuration combination of mixed energy storage economy is obtained in the case of new energy consumption rate ≥ 95%. The results show that the proposed method can effectively simulate the annual output curve, promote the consumption of new energy and improve the economy of operation. © 2024 IEEE.

Due to the influence of global warming, extreme wind weather occurs frequently, especially in extreme weather such as typhoons and cold waves, problems such as wind turbine shutdown, cutting out, and sudden changes in power generation power will occur, which brings great challenges to wind power forecast and safe and stable operation of the power grid. At present, the research and analysis of strong wind weather mostly stay at the single fan level, and the causes of abnormal changes in wind power output are mostly analyzed from the physical level. However, with the large-scale access of wind power to the power grid, the impact of extreme weather on power grid operation is becoming more and more significant, and it is particularly important to study the impact of strong wind weather events on wind power cluster output. This paper summarizes various types of wind power generation weather events, then screens key meteorological factors affecting power generation under different wind weather conditions based on Gaussian search and grey correlation weighting, and finally analyzes the meteorological impact on the actual operation of wind farm stations and clusters under typhoons and cold waves respectively, aiming at the problem of huge deviations in wind power forecast caused by wind. The next research direction and suggestions are put forward. © 2024 Published under licence by IOP Publishing Ltd.

Based on the basic principle of multi-objective, multi-criteria, multi-factors and multi-level decision-making, a comprehensive evaluation system suitable for photovoltaic power generation units is proposed, which considers the advantages and disadvantages of objective weight method and subjective weight method. The minimum deviation combined weighting method is used to calculate the combined weight, and then the comprehensive performance evaluation model of photovoltaic power generation unit is established.

With the rapid development of renewable energy power in China, the accommodation of renewable energy has faced a new challenge. The Large-scale battery energy storage system (BESS) is a promotive way to improve the accommodation of renewable energy. In this paper, a method for power rating and capacity optimization of BESS is proposed based on sequential production simulation technology. An optimization model is established to maximize the utilization of renewable energy, considering constraints of system power balance, the operation mode of BESS, and conventional units. The annual hourly curtailment time sequence of renewable energy is incorporated as inputs with the target of utilization rate as constraints for optimizing the power rating and capacity of BESS. In the case of studies, an annual hourly curtailment time sequence in a province of China is tested, and the optimal power rating and capacity of BESS of the province are obtained. The testing results verify the effectiveness of the proposed method. © 2022 IEEE.
