The constant droop coefficient (DC) in the traditional f-P and V-Q droop control is not conducive to the state-of-charge (SoC) management of the battery energy storage (BES) system. This paper proposes an improved droop control strategy (DCS) for the power grid which considers both the power frequency adjustment of the power system and the SoC management constraints of the BES. The proposed improved DCS is enabled to adjust the DC according to the SoC status of the BES. Case studies verify the effectiveness of the proposed DCS, which significantly reduces the frequency change deviation in the dynamic process of the weak power grid. © 2023 IEEE.

Light gas protection only operates when gas within the transformer collection chamber reaches threshold volume. Such criterion failed to reflect transformer conditions accurately due to the lack of understanding for defect developing process and corresponding gas generation- convergence pattern, which has led to lower protection reliability and has caused several transformer explosions. To address current problem, an experimental tank with structure resembling that of a power transformer is set up, inside which the needle-plate oil-pressboard breakdown model is planted. Experimental results indicate that throughout fault development, voltage drops became more frequent until arcing occurs, so is HFCT signal;meanwhile gas generation rate increases through slight partial discharge, spark discharge and arcing stage, the collected gas volume corresponds with patterns above. The purpose of this study is to clarify the defect developing process and the gas generation-convergence pattern for oil-immersed transformer internal fault in guidance for a more reliable protection method. © 2021 IEEE.

To effectively cope with the problems of surging data volume, high data acquisition cost, and congested communication transmission in distribution networks containing distributed new energy sources, this paper proposes a short data window data acquisition and intercommunication scheme based on compressed sensing theory and builds a corresponding model with the distribution network longitudinal differential protection data intercommunication process as a specific research scenario. The paper analyzes the shortcomings of the Gaussian random matrix, a universal observation matrix commonly used in traditional compressive sensing, in the distribution network, and constructs a deterministic matrix for the current signal characteristics of the distribution network to solve the problem of data reconstruction in the application of compressive sensing in the field of the power system. The problem of unstable recovery is solved. In addition, a sparse base satisfying the constrained isotropy condition is selected from the commonly used sparse bases for the constructed deterministic observation matrix, and a tracking algorithm with unbiased estimation is combined to design a targeted data compression reconstruction algorithm that can apply the compressive sensing theory to the distribution network longitudinal differential protection information intercommunication scenario in a more suitable way. This algorithm has a significant improvement in reconstruction accuracy, and the reconstruction time is short and adaptable to the real-time current signal of the distribution network. © state grid Electric Power Research Institute 2023.

The protection link within the wind farm is the key link that affects the transient characteristics of the wind farm, and also has the greatest impact on the complexity of scene construction. Therefore, it is urgent to study the method that can quickly build the chopper circuit and crowbar circuit action scene during the evaluation of the equivalent model of the wind farm. In this paper, a fast generation method of wind farm protection state scenarios based on Deep Belief Network (DBN) is proposed. Firstly, characteristic quantities that affect the protection action of a single fan in a wind farm are extracted, such as terminal voltage drop (the junction voltage of a single fan is equal to the terminal voltage), wind speed, etc. Simulation is carried out on a single fan in scenarios with different characteristic quantities, and records of characteristic quantities and protection actions are put into the DBN model for training as a sample set. Through training, a DBN model which can directly and accurately generate the fan protection state according to the characteristic quantity is obtained. Then, the topological structure and line impedance information of the wind farm are obtained, and the relationship between the voltage drop at the junction point and the voltage drop at the end of each fan in the wind farm is obtained. Combined with the voltage drop at the end of each fan in the wind farm and the deep belief network model, the fan protection action scene in the wind farm can be quickly generated for equivalent model evaluation. Finally, a numerical example is given to verify the effectiveness of the proposed method. © 2023 IEEE.

Modern power systems with high penetration of renewable energy enrich the frequency regulation resources by offering more new clean wind and solar energy. In this paper, we present a bottom-top design of wind park's participation in the frequency regulation market considering the complementarity of wind park power outputs. By defining a quantitative complementarity index, we show how the complementarity contributes to the regulation reserve reliability of wind parks and the consistent market performance, and verify the conclusions via numerical analysis. © 2022 IEEE.

With the wide application of power semiconductor devices in severe working conditions, the reliability and lifetime estimation of power semiconductor devices have become the research hotspot. Power cycling test is a significant method to study the reliability issues. This paper first analyzes the existing methods and then proposes a new power cycling method which considers not only realistic electrical conditions but also the thermal stress from different regions. Firstly, rainflow algorithm is used to extract the temperature cycles with large amplitude. Next, the junction temperature cycles and case temperature cycles are matched using integer programming algorithm and modified by means of equivalent substitution. At the same time, a method to control the case temperature and the junction temperature simultaneously is proposed. Afterwards, modified rainflow reconstruction algorithm is used to combine these matched cycles to temperature arrays. Finally, test load profile is formed. An electric vehicle motor drive system based on the Worldwide Harmonized Light Vehicle Test Procedure mission profile is used to verify the proposed method. This method can simultaneously stress the bonding wire and the solder layer, which provides a new way to access the reliability of power devices in real application. © 2021 IEEE.

In combined cooling heating and power system, the gas-steam combined cycle is gradually used more and more. The common operation mode in CCHP is mainly to determine heat by electricity and heat by electricity. This paper defines an index indicator and analyzes the difference between the two operating modes in different intervals through the system energy supply interval chart, finally analyzes the difference in the indicators between the two operating modes through the actual load method. It is concluded that in winter operating conditions, the following the thermal load (FTL) operation mode is better;in summer operating conditions, the indicator of following the electric load (FEL) is better;during the transition season, the value of PEC is better in the case of following the thermal load. © Published under licence by IOP Publishing Ltd.

The grid structure of the modern power system is complex and the space span is large. When the power system is disturbed to generate unbalanced power, the transient distribution process among the various synchronous units leads to the spatiotemporal distribution characteristics of the frequency response of the system. By measuring the generator Frequency and Inertia, the inertia center frequency can be calculated. Based on the two-generator system, the relationship between generator frequency and bus frequency is analyzed. A method for selecting the frequency inertia center node of the local power grid in the power system is proposed, and the inertia center frequency of the system is estimated based on the measured frequency at this point. Taking 10 machines and 39 nodes as an example, the simulation calculation is carried out to verify the effectiveness of the proposed method. © Published under licence by IOP Publishing Ltd.

An accurate wind farm model is a crucial prerequisite to ensure that the simulation results of the power system containing wind power align with reality. Hence, it is imperative to establish a system for evaluating the accuracy of wind farm models. This paper examines the fault response characteristics of wind turbines and proposes a multi-dimensional quantitative index system for assessing the equivalency of wind farm models. The entire process can be segmented into two stages: the transient period immediately following the fault occurrence and the subsequent steady-state phase. The evaluation indexes for assessing the accuracy of wind farm models are voltage dynamic response, active power dynamic response, and reactive power dynamic response. These indexes are formulated to evaluate the equivalency of wind farm models across various stages. © 2023 IEEE.

This paper describes the corresponding control strategies for the normal and fault operation states of the islanded microgrid system. The islanded microgrid system consists of distributed energy resources (DER) such as photovoltaic (PV), hybrid energy storage (HES) and microturbine (MT) and loads such as pumping unit load (PUL) and equivalent load. In the normal condition, it adopts a voltage and frequency (V-f) control strategy for the inverter of MT to maintain constant voltage and frequency of the whole system and a constant power control strategy for the rest of the power inverters. In the fault condition, the front and rear stages of the PV system adopt constant power control and reactive power compensation priority control respectively, thus realizing low voltage ride-through (LVRT). The proposed control strategies can ensure the stability of voltage and frequency of the microgrid during normal conditions and the ability of the PV system to achieve LVRT during fault conditions. A simulation model of the islanded microgrid system based on PSCAD/EMTDC is constructed and the effectiveness of the control strategies under normal and fault conditions is verified. © 2024, state grid Electric Power.
