Especially when AC grids are weak, improper capacity planning in a renewable energy generation base, which is by nature a multi-infeed power electronic system (MIPES), may lead to potential dynamic stability issues such as small signal instability. Therefore, the allocation of the total grid-connected renewable generation capacity among feeding points in a MIPES plays a significant role in managing the risk of instability issues. In this paper, a method is proposed to optimally allocate the given total grid-connected renewable capacity at each feeding point in a MIPES in order to maximize the small signal stability margin. The proposed method is finally validated via both eigenvalue analysis and time-domain simulations.","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":"121116954","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}

In this paper, an innovative Affinity Propagation clustering algorithm is proposed and improved in load curve clustering to analyze demand response potential effectively. First, the feature indices of load curve are extracted to reduce data dimension. In the face of the weakness of subjective weighing, Entropy Weighting is introduced to objectively determine the weight of load feature indices. Then, Preference parameter of AP clustering algorithm is adjusted by local search mechanism to improve the similarity calculation, and the convergence of clustering result is ameliorated by DB index. Based on the clustering result, the feature indices are combined to analyze the demand response potential of customer. Case studies show that the proposed algorithm has good performance in both the clustering efficiency and effect, and the extracted features are beneficial to consumption behavior analysis.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"9 1 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":"129780060","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}

Both of the complexity of and demand for better voltage regulation are increasing. AVC system is the most famous system-wide Q/V control system which consists of PVC, SVC and TVC. SVC controls the voltages of buses within a control zone by sending individual set-point values to PVCs belonging to the control zone. Traditional SVC assumes that PVCs within a control zone is decoupled and each PVC can reach the set-point value during a control period. However, the proof in this paper reveals the fact that if there are strongly coupled PVCs in a control zone, the competition between those PVCs will cause unreasonable reactive power flow. PVCs can’t reach their set-points so a deviation of Q output is induced. In this paper, a novel SVC model is proposed so as to eliminate the Q deviation. Simulation work verified the proof and demonstrated the effectiveness of the proposed SVC model.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128978415","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}

An attacker is able to manipulate the integrity of real-time data by maliciously modifying the readings of meters transmitted to the control center. Moreover, it is demonstrated that such attack can escape the bad data detection in state estimation if the topology and network information of the entire power grid is known to the attacker. In this paper, we propose an isolation forest (IF) based detection algorithm as a countermeasure against false data attack (FDA). This method requires no tedious pre-training procedure to obtain the labels of outliers. In addition, comparing with other algorithms, the IF based detection method can find the outliers quickly. The performance of the proposed detection method is verified using the simulation results on the IEEE 118-bus system.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"14 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":"124124569","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}

Practice has proved that the design and formulation of daily dispatching plan of power system is an important part of power system design, which must be paid attention to and done well. With the increasing scale and complexity of Chinese power grid, the formulation of power grid dispatching plans is inefficient and inaccurate, sometimes blindly. In this paper, the problem is studied, and a quasi-steady-state simulation intelligent assistant method for Power Grid Dispatching Planning is proposed. The dispatching plan makers can first make a rough dispatching schedule, and then use this method to track the trend from the first dispatching plan point to the next plan point one by one, and the operation information of each component can be displayed in the power grid in real time. The dispatching and operating personnel of the power grid can fully understand the characteristics of the corresponding dispatching plan point as well as transition between points and points, so as to help makers to perfect power network dispatching plan in an all-round way and develop a shorter time scale scheduling plan. This method can approximately simulate the real power flow fluctuation. The effectiveness of the proposed method is verified by the simulation calculation of some year national interconnection data. Based on Power System Analysis Synthesis Program (PSASP), the method proposed in this paper is implemented, and the detailed design of intelligent checking power grid dispatching plan using this method is presented.","PeriodicalId":257974,"journal":{"name":"2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia)","volume":"56 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":"134371432","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}

Then an interval characterizing the voltage sag tolerance of the sensitive process can be obtained by analyzing and calculating the proposed indexes.
