The novel analytical model, based on the Maxwell's equations and assisted by a magnetic equivalent circuit (MEC), is adopted in order to calculate the essential performance indices (PIs) including the average torque, torque density and efficiency. The proposed model prevails over the prevalent finite element analysis (FEA) in terms of calculation speed, while maintains the accuracy of the calculation results. The multi-objective particle swarm optimization (PSO) and the differential evolution (DE) algorithms are both applied to find the Pareto front. Influences on the Pareto front caused by the parameters in the algorithms are also discussed. Two optimal designs are chosen from the Pareto front for further validation through FEA simulation. The proposed optimal design method is capable of finding the optimized SynRM designs subject to various design requirements and is able to accelerate the entire optimization process.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124138364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model has a similar structure to the classical model in that it comprises two dynamic states, the power angle and the angular speed. However, unlike the classical model, the model finds applications beyond first swing stability analysis; for example, they can also be utilized in transient stability studies. The model is developed through a systematic model-order reduction of a nineteenth-order state-space model by using singular perturbation techniques. It is validated by comparing its response with that of the nineteenth-order model and that of the classical model.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134366448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The entire problem is formulated as a bi-level optimization process, where the structure of all markets is modeled considering the joint operation limits. The strategic bidding behavior of a price-maker BESS in a pay as performance regulation market is investigated. Additionally, a specific approach is introduced for modeling automatic generation control (AGC) signals in the optimization. Although the formulated problem is non-linear, it is converted to mixed-integer linear programming (MILP) to find the optimum solution. The proposed framework is evaluated using test case scenarios created from real-world market data. Case study results show the impact of BESS's price-making behavior on the joint operation of energy, reserve, and regulation markets.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132725283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The co-simulation framework introduces iterative coupling and unbalanced transmission system analysis that help accurately replicate the standalone T&D system results without resorting to the computational challenge of developing large-scale standalone T&D models. The integrated T&D systems are evaluated for multiple PV deployment scenarios based on randomly generated PV locations and sizes.

Because the solar radiation changes continuously throughout the day, it also changes the maximum power point on the voltage scale of the photovoltaic module. Hence the tracking of the global peak is important for efficient power withdrawal from the PV Array. The proposed algorithm calculates the different duty cycles near to all possible maxima, which apply to different solar irradiance at different time. Then select a duty cycle near to the maximum power available at that time. The Perturb and Observe (P&O) approach is applied at the selected duty cycle to achieve GMPP. The simulation studies are performed for different conditions of irradiance. The ideal single-diode model (ISDM) is used for modeling the photovoltaic (PV). For the effectiveness of the proposed method, it is compared with the conventional Perturb and Observe (P&O) for the different PSCs.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131271862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Smooth integration is required during start up and re-connection of the SST. Smooth disconnection of the SST is required during islanding of a part of distribution network. SST model must remain stable during both the processes. A distribution test system is used to evaluate the performance of the proposed SST model during start up and disconnection processes.

Yunnan Power Grid is a typical direct-current (DC) sending grid and the installed capacity of hydro-generators has accounted for more than 70% of the total capacity after asynchronous interconnection between Yunnan Power Grid and China Southern Power Grid in 2016. But the high hydropower proportion of Yunnan Power Grid makes ultra-low frequency oscillation (ULFO) more prone to occur. Battery Energy Storage System (BESS) has broad application prospects in frequency regulation. Aiming at the ULFO problem caused by AGC daily operation, a coordinated AGC strategy based on BESS is proposed. It is able to eliminate ULFO caused by AGC action by ramping the AGC signal assigned to the units and self-adaptive action of BESS with a small energy storage capacity once the system is judged to be at risk of oscillation.

In this paper, we address the challenges related to variable power generation profile from PV resources leading to voltage fluctuations at the secondary feeder level. The objective is to develop local smart inverter control methods to reduce the voltage fluctuations at distribution buses using reactive power support. Towards this goal, an approach based on the power flow measurements of the lines connected to the PV generation buses and the local PV generation measurements is proposed to obtain the required reactive power support to mitigate voltage fluctuations. The proposed method is validated using two three-phase unbalanced test systems: IEEE-123 bus and the modified R3-12.47-2 taxonomy feeder with 329-buses. It is shown that the proposed local control approach is effective in mitigating voltage violations resulting from large changes in active power injections of the PV generators and in reducing overall voltage fluctuations due to PV generation variability. Further, it is validated that the proposed local control approach results in a better performance with regard to decreasing the voltage fluctuations compared to a standard Thevenin impedance-based method.","PeriodicalId":175719,"journal":{"name":"2019 North American Power Symposium (NAPS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116168059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
