In this paper, primary frequency regulation (PFR) performance and the mechanism of this new technology are studied. A battery hybridized hydropower plant (BH-HPP) model, based on a field-measured-data-based hydropower plant (HPP) model and a verified battery simplified model, is established. Analysis of system stability and dynamics is undertaken for three different battery control strategies by root locus and participation factor methods. Compared to conventional HPPs, analysis results theoretically reveal BH-HPP can not only accelerate system regulation rapidity but also effectively enlarge HPP stability region during PFR process. Time domain simulation verifies the results and further shows synthetic control has better performance among introduced strategies. Besides, initial design ranges of control parameters considering battery capacity and a renewable energy source scenario case are also discussed. This work could provide theoretical support for flexibility enhancement solutions for hydropower systems.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"10 5","pages":"2127-2137"},"PeriodicalIF":6.9,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10106212","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A constant dc-link voltage is usually assumed in existing literature to estimate transient stability of virtual synchronous generators (VSGs). However, actual power supply in the dc-side of VSGs is limited and different dc-link voltage controllers are needed to achieve power balance between DC side and AC side. Addition of dc-link voltage controller has great influence on transient behavior of VSGs, which has not been investigated by previous research. To fill this gap, this paper gives insights into the effect of dc-link voltage dynamics on transient stability of VSGs. First, two typical kinds of VSGs with dc-link voltage controllers are introduced. Then, mathematical models considering dc-link dynamics are established and the effect of dc-link voltage controllers on transient synchronization stability of VSGs is revealed through equal area criterion (EAC). It is found that dc-link voltage controller would reduce stability margin of VSGs and design-oriented transient stability analysis is carried out quantitively using critical clearing time (CCT). Finally, simulation results are given to validate correctness of theoretical analysis.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"10 2","pages":"593-604"},"PeriodicalIF":7.1,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10106201","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140351444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low electrical tracking/erosion and poor flame resistance performance of silicone rubber once ignited, substantially reduce its working life. This paper attempts to investigate tracking/erosion performance of room temperature vulcanized (RTV) silicone rubber along with flame retardant parameters using aluminum trihydrate (ATH), graphene nanosheets (GN) and milled glass fiber (GF) additives. The inclined plane test (IPT) was performed in line with criteria defined in IEC 60587 using step-up tracking voltage method while flame retardancy is evaluated according to ASTM E 1354.0 using a cone calorimeter. Results suggest 30% of ATH assists in improving physical tracking/erosion resistance of pristine silicone elastomer rubber by impeding development of leakage current and a great reduction in maximum average temperatures on the surface of RTV2. Further improvement in performance of RTV2 is achieved through introduction of 1% of GN and 5% of GF as seen in RTV4. Moreover, 30% of ATH reduces heat release rate and smoke production rate, and this trend is improved with the introduction of GN/GF. RTV4 has pop up as the most promising silicone rubber composite with excellent electrical tracking, erosion, and flame resistance performance relative to its counterparts in this study.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"9 5","pages":"1918-1925"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/7054730/10288371/10106211.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50327610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this issue, this paper proposes a coupon-based demand response (CDR) scheme to achieve equivalent dynamic retail prices to inspire consumers' inherent elasticity. First, a security-constrained unit commitment optimization model is developed in the day-ahead market to obtain coupon rewards, which are then broadcast to consumers to motivate them to reschedule their power consumption behaviors. To evaluate the adjustment value of consumers' power consumption, a collective utility function is proposed to formulate the relationship between power quantity and coupon rewards. On this basis, the security-constrained economic dispatch model is developed in the intra-day market to reschedule generating units' output power according to real-time load demands and fluctuating renewable energies. After the operation interval, a settlement method is developed to quantify consumers' electricity fees and coupon benefits on a monthly basis. The proposed CDR scheme avoids real-time iterative bidding process and effectively decreases the difficulty of massive, small consumers participating in DR. The proposed CDR is implemented in a realistic DR project in China to verify consumers' energy cost and renewables' curtailment can both be decreased.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"10 5","pages":"1887-1900"},"PeriodicalIF":6.9,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10106189","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142397509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a new business model of the MSIS, with substations as the carrier, integrating distributed photovoltaic, energy storage, electric vehicle charging, data center, and 5G base stations is proposed. From the social environment, natural conditions, and complementary characteristics, a comprehensive index system is established to analyze expansion capability of substations and multi-station combination scheme. Scenario reduction is performed by extracting feature vectors and building a comprehensive evaluation function to select the optimal combination scheme under a specific scenario. Moreover, for the combination scheme in a specific scenario, the optimal capacity configuration and coordinated operation strategy chance-constrained programming model of the MSIS are established under different operating conditions.

However, uncertainties of solar energy and load affect safe and stable operation of the ship microgrid. In order to deal with uncertainties and real-time requirements and promote application of ship zero-carbon energy, we propose a real-time energy management strategy based on data-driven stochastic model predictive control. First, we establish a ship photovoltaic and load scenario set considering time-sequential correlation of prediction error through three steps. Three steps include probability prediction, equal probability inverse transformation scenario set generation, and simultaneous backward method scenario set reduction. Second, combined with scenario prediction information and rolling optimization feedback correction, we propose a stochastic model predictive control energy management strategy. In each scenario, the proposed strategy has the lowest expected operational cost of control output. Then, we train the random forest machine learning regression algorithm to carry out multivariable regression on samples generated by running the stochastic model predictive control. Finally, a low-carbon ship microgrid with photovoltaic is simulated. Simulation results demonstrate the proposed strategy can achieve both real-time application of the strategy, as well as operational cost and carbon emission optimization performance close to stochastic model predictive control.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"9 4","pages":"1482-1492"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/7054730/10213441/10106187.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50425461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently developed SCMLIs enable single-stage voltage boosting, as well as inversion resulting in step-up ac output. Towards reduction in number of components, this paper introduces a boost type single-source nine-level (9-level) SCMLI employing two capacitors and three diodes. Owing to the series-parallel connection process, capacitor voltages are inherently balanced and assist in quadruple voltage boosting from a single-source. Maximum voltage stress across semiconductor devices is limited to twice input voltage only. Using a minimum number of components, the proposed SCMLI can be extended to increase voltage levels without additional dc input. Each extension module adds two additional voltage steps in the output while maintaining maximum voltage stress the same as 9-level circuit. Followed by in-depth analysis of circuit operation and power losses, a thorough comparison of recently developed single-phase 9-level MLIs is carried out, which verifies design superiority. Extensive simulation and experimental results are presented to verify the prominent features of the 9-level SCMLI under dynamic operating conditions.","PeriodicalId":10729,"journal":{"name":"CSEE Journal of Power and Energy Systems","volume":"9 5","pages":"1688-1697"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/7054730/10288371/10106209.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50327605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
