However the forecasted wind power and speed are full of uncertainty. Considering this point, a WF dynamic multi-machine equivalence method is presented for the power system dispatch early warning calculation. The joint probability density functions (PDFs) of wind power and speed errors in forecast are selected as clustering index. The improved KL distance is applied to evaluate the similarities among the wind power forecast error distributions of all WTGs. All WTGs are divided into several groups by k-means algorithm. The WTGs and lines in each group are equivalent to a single-machine equivalent model. Considering both inaccurate and accurate scenarios of wind power forecast in the simulation case, the WF output responses curves of the detailed model, the conventional equivalent model and the proposed equivalent model are compared. The result indicates that the proposed equivalence method has better accuracy when the forecasted value is inaccurate.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122580936","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}

Based on equivalent three machine system model, this paper deduces the function expression of voltage amplitude and position of multi-frequency oscillation center. The function is affected by power potential amplitude ratio, line impedance, frequency of power potential and initial phase of power potential. Thus, the performance of the out-of-step splitting device is influenced by the change of operating mode and migration of oscillation center affect. Therefore, the out-of-step splitting device cannot be well applied in the multi-frequency out-of-step scenario. On this basis, this paper proposes a new out-of-step splitting strategy for oscillation center migration under multi-operation mode based on WAMS information. In detail, the proposed strategy can obtain bus voltage amplitude/phase information provided by WAMS and local Ucosφ criterion to determine position of out-of-step oscillation center and out-of-step period. The simulation results show that the influence of different power system operation modes on the migration characteristics of oscillation center is correctly applied in multi-frequency out-of-step oscillation scenario, and the proposed strategy based on WAMS information has a good adaptability under different operation modes.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133179962","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}

Firstly, PNP technology of BESPS is divided into two dimensions: energy flow level to achieve ‘plug’ goal and information flow level to achieve ‘play’ goal. Then, advanced applications in energy flow level are given, which include conversion control between grid-connected and off-grid, active voltage and frequency support, load peak shifting. The basic principles of establishing BESPS grid-connected communication model and communication mechanism based on information flow are first proposed. The communication interaction method with the example of between Control Center of Power Station (PSCC) and Power Dispatching Center (PDC) is analyzed. the compatibility of BESPS can be improved by researching the basic ways of device interface interoperability, which includes two parts: battery to Energy Storage Unit (ESU), ESU to BESPS.

The change-rate matrix is used to solve the reactive power compensations of PV nodes, thereby indirectly transforming PV nodes into PQ nodes. The derivation and solution of the fixed change-rate matrix are studied. Theory proves that there are linear relationships between the voltage corrections and the reactive compensations of PV nodes. The elements of the change-rate matrix are constant and are not related to values of the reactive compensation. The muliple power flow calculation method is used to solve the fixed change-rate matrix, which overcomes the error caused by the direct calculation of transfer reactance, thus improving the convergence of the algorithm. The proposed algorithm is validated by the IEEE 33-node system with PV-type DGs. The simulation results show that the proposed algorithm has good convergence, and the convergence of the algorithm is weakly sensitive to the number and the initial reactive power values of PV-type DGs.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124415562","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}

To improve the operation economic efficiency and acceptance of renewable energy source of the hybrid AC/DC micro-grid, it is necessary to configure battery energy storage system for distributed generation. In this paper, a mix integer optimization model of generation and storage is proposed for the hybrid AC/DC micro-grid to determine the optimal configuration of generation and storage. Taking the minimum cost of generation and storage investment as well as the minimum operation cost of power generation and purchase and sale of electricity, the dynamic characteristics of generators and storage devices are taken into consideration, and the power loss through AC/DC converter is taken into account. The model is solved as a mixed integer optimization based on Benders Decomposition algorithm. The numerical study shows that the optimal configuration of coordinated generation and storage can effectively save the investment cost of AC/DC hybrid micro-grid, which verifies the validity of the proposed model.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114654056","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}
