In order to improve the automatic generation control (AGC) performance of thermal generators, this paper presents a stochastic model predictive (SMPC) approach for battery/flywheel hybrid energy storage system (HESS) distribute power. The combines an adaptive Markov chain power demand prediction HESS, scenario tree and strategy. To develop effective deal with randomness generator in response AGC command, is used describe HESS demand, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Abstract A carbon responsibility allocation method based on the complex structure emission flow theory is proposed to address problem posed by unclear of each link in low-carbon development electric power. First, calculation method, distribution characteristics, and mechanism were analyzed. The “carbon potential structure” concept was introduced track trajectory” “green harnessing ability structures retain two-dimensional information. Subsequently, methods for network loss users’ electricity...
Due to limitations of topology, the series architecture electric energy router (SA-EER) for low-voltage distribution network (LVDN) has disadvantages that transmission range is limited 100% and reactive powers are unable operate flexibly. For this reason, a new type EER with series-parallel (SPA-EER) constructed in paper, it can break through above SA-EER. In addition architecture, two-degree-of-freedom power flow flexible control strategy (TDF-PFFCS) proposed further support realization...
Abstract Traditional on‐load voltage regulating transformer are composed of segmented windings controlled by tap changers and power frequency transformers. The changer can only perform ‘step‐wise regulation’ is slow in response. A topology flexible presented this paper, which requires connecting a electronic converter at the transformer. PEC fully combine existing to achieve continuous stepless regulation function. This paper conducts modelling switch cycle average analyses range for...
ABSTRACT Under the dual‐carbon target, distributed energy sources often cause power mismatches between supply and load, challenging stability safety of distribution networks. This paper proposes a comprehensive evaluation system for active network operation, focusing on safety, economy low carbon emissions. A cooperative optimal scheduling strategy multiple agents based stochastic programming is also introduced. The operating characteristics sources, storage loads are modelled to quantify...
The mixture unidirectional solid-state circuit breaker (SSCB) based on transistor-based devices [i.e., IGBT-based line commutation switch (LCS)] and the thyristor-based can combine their respective advantages, however, conduction loss cost may increase significantly when expanding to a bidirectional topology because number of IGBTs had be doubled with expansion LCS structure composed two groups in reverse series. In this letter, full-bridge SSCB (FB-MSSCB) requiring only one is proposed,...
To reduce carbon emissions and promote the consumption of renewables in port areas, this paper, a hybrid energy storage system (HESS) management method combined with transportation-electricity coupling characteristics ports is proposed. The proposed solves imbalance mitigates random power fluctuations through day-ahead scheduling intraday adjustment, respectively. In scheduling, load model based on berth-quay crane (B-QC) presented. Furthermore, to optimize operation economy consideration...
Each arm of modular multilevel converter (MMC) consists a large number sub-module (SM) units. However, it also increases the probability SM failure during long-term system operation. Focusing on fault-tolerant operation issue for MMC under faults, traditional zero-sequence voltage injection control algorithm is analyzed detailed and its disadvantages are concluded. Based this, novel strategy based phase disposition pulse-width modulation (PD-PWM) proposed in this paper, which has three main...
The modular multilevel converter (MMC) is now the most attractive topology for medium and high voltage power conversion applications with several advantages over traditional source (VSC). However, due to a large number of sub-modules (SMs) in MMC, system reliability big challenge its practical application, where each SM may be considered as potential point failure. In this paper, evaluation based on Markov model proposed MMC. failure rates electronic devices SMs are firstly analyzed. Then,...
Direct ac–ac converters work without dc links. They have the advantages of small volume and high reliability. However, direct cannot realize simultaneous decoupling control output voltage amplitude phase.
