SVC refers to a shunt device within the family of flexible alternating current transmission system and is widely used for enhancing voltage profile and power transmission capability. SVC along with power system stabilizer (PSS) is employed to damp out the oscillation and take back the system to a stable state following disturbance. Crow search algorithm (CSA) is implemented to optimize conventional parameters of PSS and SVC. Simulation results found by it are compared with others optimization algorithms such as particle swarm optimization (PSO) and teaching-learning-based optimization (TLBO). Also, power system model under the effect of CSA based tuned PSS and SVC is verified using eigenvalue analysis under steady state condition for investigating steady state stability. A comparative time domain simulation under MATLAB/SIMULINK platform employing CSA, PSO and TLBO tuned PSS and SVC with studied single machine infinite bus system is carried for dynamic stability assessment. Results obtained confirm the efficacy of the CSA in better tuning of PSS and SVC than other counterparts.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121559214","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}

Due to the restrictions of space near households, EV owners are required to charge their EVs at the workplace during the daytime in smart cities, which will cause proliferation of the peak load. In addition to this, the possibility of maximum output from PV generation is afternoon, which could intimate to have a significant plausible of PVs to reward the EVs charging. Proposed smart charge scheduling of EVs depends on usage of PV can mitigate both the detrimental impact of the charging EVs on the distribution network and charging constraints. For rewarding the unrestrained EVs charging, quantity bound in terms of maximum number of EVs with unrestrained charging are deliberated through maximum consumption of the PV generation. Remaining percentage of EVs are charged from the grid subjected to grid constraints. Then, for these EVs, the regulated charging is scheduled with line loss minimization as the optimization objective. To validate the reduction of the peak load of the demand profile and growth of number of EVs through unrestrained charging, a realistic case study is incorporated in the proposed scheme.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124036695","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}

During islanded mode also, the fault magnitudes are significant and call for efficient and fast protection schemes. The coordination protection devices, especially, directional overcurrent relays (DOCRs) is a vital issue when dealing with microgrids with SDGs. In addition to the connection of DGs, frequent line outages affect the DOCR settings and cause device maloperation leading to miscoordination issues. This paper deals with optimal coordination of DOCRs for microgrids considering DG and line outages. A coordination model is proposed which involves the constraints corresponding to all N-1 contingencies, which can be a result of line / DG outage. In addition, cases of multiple fault locations are also included in the model to provide effective settings under all circumstances. The problem is modeled as a linear interval programming (ILP) problem and solved using invasive weed optimization (IWO) method. The ILP problem is stated as a sub-problem to IWO which would make it a hybrid optimizer. The proposed method is tested on 9 bus microgrid test system and results are presented.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"121 3 Suppl 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128493240","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}
