The accelerated proliferation of Solar Photo-Voltaics (SPV) in distribution networks, has resulted in voltage fluctuations in the distribution system. This is due to the high R/X ratio in Low Voltage (LV) distribution network that leads to strong coupling between active power and voltage. This paper thus proposes coordinated control of voltage in LV distribution systems by On-Load Tap Changer (OLTC) and Battery Energy Storage Systems (BESS) so as to mitigate the issue of voltage rise/drop. The objectives are to operate the slow-acting OLTC in the presence of fast-acting BESS and reduce the stress on battery charging/discharging. This leads to increase in battery life and reduced operation of OLTC, which helps in utility asset optimization in terms of both the OLTC and BESS. In the proposed scheme, OLTC tap operation is based on the weighted average of the bus voltages. The feasibility of the proposed approach is demonstrated on a modified IEEE 13 node distribution system which is simulated in MATLAB/Simulink. Simulation results verify the proposed coordination voltage control scheme.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"38 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":"132884809","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 induction machines employed in the wind farms possess different characteristics compared to conventional synchronous generator plants. The behaviour of these induction generators, can affect the stability of power system when they operate in synchronism with synchronous generators. Also, the frequency response of the power system has been deteriorated with integration of converter based wind turbine generators because of their inability to provide natural inertial response. One of the remedies for this can be to operate the doubly fed induction generators (DFIG) as a synchronous generator to provide inertial response during frequency event. In the literature, small signal stability has been analyzed for the SMIB system integrated with the wind farm. This paper offers small signal stability analysis of multi-machine power system integrating DFIG based wind farm. It further analyzes the changes in small signal response and frequency improvement while the DFIGs are operated in order to emulate the synthetic inertia. Detailed modeling of the wind generators and their integration with the multi-machine system is presented in this paper. Eigenvalue analysis has been performed for it and the effect of DFIG based wind farm on the frequency oscillations and damping of the system is discussed.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"40 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":"130488453","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}

It is also essential to devise the generation systems in such a way as to optimize the usage of all the available resources in the area with minimum dependency on non-renewable sources. The system design should also consider the costs involved for installation, generation and maintenance and make it affordable to the common masses to ensure effective utilization. This paper proposes a power management algorithm of a microgrid comprising of PV, wind, DG and a battery. The complementary nature of wind and solar power gives the advantage that the availability of renewable energy is there throughout the day, thus reduces the usage of DG. The microgrid is optimally sized using PSO algorithm. The power management algorithm runs in two stages, source side management and Demand side management. The inputs to the source side management algorithm are original load schedule and renewable forecast for the day. The output of the algorithm shows the contribution of each source over the day. The DSM algorithm analyzes the usage of various sources and shifts parts of loads to reduce the DG usage. The strategy is intelligent as it checks the availability of renewable energy and dynamically shifts the load so that DG usage will be minimized.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"5 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":"126653522","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 communication-assisted distance protection schemes are extensively used for protection of these lines. The presence of a third source-terminal causes under-reach and overreaching problems and increases the challenges during the protection of these lines. The proposed protection method uses synchronized measurements of voltage and current phasors, measured at three ends of a three-terminal transmission line. These measurements are further used to calculate voltage at the tap point. Then the superimposed voltage components are calculated at the tap point and at three terminals for both the parallel circuits. The method compares a maximum among the superimposed voltage phasor component calculated at the tap point with the maximum among the superimposed voltage phasor components measured at the three terminals of the line to identify the faulty line. A 400-kV three-terminal mutually coupled double-circuit test system is simulated in ATP/EMTP environment and the scheme is verified in MATLAB. The simulation results confirm the superiority of proposed scheme.","PeriodicalId":185930,"journal":{"name":"2018 20th National Power Systems Conference (NPSC)","volume":"38 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":"133252050","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}
