As the EHV transmission network of India is spread across the length and breadth of the country, it is quite natural that the national grid too is subjected to different climatic conditions. Even different parts of the same overhead 765 kV or 400 kV long line experience different weather conditions at the same time, as the line passes through different weather zones. Depending upon the season, the transmission network is exposed to different extreme weather conditions. Though the overhead lines are well designed to endure these diverse weather conditions while maintaining reliability margin, but their performance is to some extent influenced by the climatic condition. One of the performance indices is its loss. The ohmic loss is dependent on the power flow and not much affected by weather. But corona loss which takes place in EHV transmission network is greatly influenced by the weather condition and seasonal change in the country. This paper aims at identifying the area in the eastern grid of the country where corona loss variation is more in different season. Some measures to minimize such loss are also suggested.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"110 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":"115734914","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 power electronic interface in this system is built using a diode-rectifier, a dc-to-dc step-up converter and a dc-to-ac multi-level voltage source converter. This paper proposes the application of a 1-phase 5-Level Active Neutral-Point Clamped Converter (1P-5L-ANPCC) as the dc-to-ac converter in the WPGS. Phase disposition and shifting pulse width modulation technique with capacitor voltages balancing has been implemented to generate switching pulses for 1P-5L-ANPCC. To control the tip-speed ratio of the wind turbine, a closed loop controller is presented. The grid active power flow control is achieved using a modified Synchronous Reference Frame (SRF) closed loop controller for 1P-5L-ANPCC. In this paper, the closed loop controller also features a grid power factor regulation scheme, which is sometimes required in a weak distribution system. Hence, a separate D-STATCOM may not be needed in this system to supply the required reactive power. The proposed WPGS with its control scheme is verified using PSCAD software simulator for a 10-kW wind-turbine. The simulation results obtained are presented to verify the working of proposed WPGS using the 1P-5L-ANPCC. The power factor regulation feature of the controller is also verified using PSCAD and corresponding results are presented.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"67 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":"116629389","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 justify the large deployment of the microgrid concept, economic operation should be guaranteed. But non-linearities present in the nature of microgrid components and network make the scheduling process complex. Again, non-linear solution strategies do not guarantee global convergence. Therefore, efficient but linear model for microgrid resource scheduling algorithms are gaining interest in present time due to its simplicity and fast computation. On the contrary, for peak demand management, flexible load scheduling is a viable and easiest option to the microgrid operators to minimize the customers' dissatisfaction. This article serves the aforementioned purposes by designing a linear model for microgrid scheduling by implementing demand side management strategies to manage flexible appliances aiming for peak demand reduction. The strategy is implemented on a practical Indian distribution system consisting of commercial and residential loads to prove its efficacy.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"12 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":"115044138","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 power system planning approach/methodology at large depends on first move of either generator or transmission planner. It requires co-ordination between generator and transmission planner and if a centralized planning regime exists, then the outcome is theoretically expected to be more efficient. With generation under competition and a delicensed activity coupled with electricity markets, transmission system planning faces further challenges. The heuristic/iterative methods seem to be efficient for small and growing system. At present, power system size has been increasing enormously and it is still growing. Effective and efficient planning in such a big complex system inevitably requires automation techniques. Various computation technique or algorithm are being explored i.e., Graph/Network theory, in power system applications or for populating the best possible combination for planning of transmission lines. This paper is presenting an Indian case study of Northern Region power system planning applying the principle of Tellegen's theorem. The suitable candidates for transmission line based on short length and optimal power flow are proposed. These best possible combinations of lines can be optimized further depending on planner requirement with other methodologies.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"1 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":"129131781","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}
