Considering the impact of the interaction between grid and wind farm on the system stability, a large-scale power grid model based on actual data and a wind farm model including electromagnetic transient are built in DIgSILENT PowerFactory. The small-signal analysis method is applied to study this system and find the possible stability influencing factors, which are the input wind speed and control parameters of Wind Turbine Generators (WTGs). Simulation results show that the access of wind farm and changes in wind speed or control parameters under weak grid will affect the system stability.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133103811","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}

This work investigates synchronous reluctance machines using a stator cage winding and the impact of its number of stator bars on the torque ripple. Firstly, the electromagnetic properties of a stator cage winding are discussed. Secondly, the output torque is calculated analytically based on principle of air-gap shear stress. Suitable combinations of number of stator bars and pole pairs are derived to reduce the torque ripple without additional sensitivity analysis or numerical optimization procedures.

Firstly, a unified PF of AC/DC system with voltage source converters (VSCs) is established. Then the IPF in AC/DC system is converted to nonlinear optimization problems based on AA under rectangular coordinate. The constraints are constructed by characteristic equations of AC/DC system, which is composed of AC grids, VSCs and DC grid. The objective functions are obtained by solution formulas of PF accordingly, which mainly includes bus voltage magnitude.

In the presented framework, individual PEV owners propose charging bids to minimize the charging cost. The proposed bids depend on the charging urgency and the day-ahead electricity price forecast. Considering the scalability of the system, aggregators at the node-level are designed to collect the bids for a group of PEVs within a node and submit a combined bid for the node to the market in a distribution network. The market clears the electricity price based on the bids, grid constraints, and the day-ahead electricity price. When the received power from the market is less than that of the total PEV power demand, power dispatch is required to effectively allocate the available power to individual distribution nodes and PEVs. Economic power dispatch algorithms are designed to minimize grid power loss and the difference of bidding cost and actual charging cost. A case study shows that the PEV charging cost and the overloading of the distribution network can be reduced significantly with the presented method.","PeriodicalId":241317,"journal":{"name":"2019 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126046959","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}

First, we modify the iterative K-means clustering algorithm to extract appliance states. Then, each state time probability distribution is extracted using the historical data. Super states are constructed based on appliance state combinations, and further reduced via learning from historical data. Super states clustering is performed considering power overlap. While performing load disaggregation, optimal solution is searched by maximizing the time probability.

Firstly, the model considers the investment of energy storage devices, taking the minimum investment and operation cost of electro-thermal coupling system as the optimization objective. The planning model takes into account the investment constraints of energy storage systems and the operation constraints of energy conversion devices. Secondly, the power balance constraint is expressed as a chance constrained to ensure the safe and reliable operation of the system. The moment uncertainty based distributionally robust method is used to deal with the uncertainty of wind power. Then, the DRCC model is established. In addition, The DRCC model is transformed into a second order cone programming model by the CVaR approximation method and duality theorem. Finally, the model is solved by CPLEX in MATLAB.

This optimized utilization of inverter capacity ensures the maximum injection of active power compared to other VS controls under similar network conditions.
