The weights of the MLPNN are dynamically adjusted online using backpropagation method and its performances are compared with the integral controllers whose integral gain and speed regulation parameter are simultaneously optimized using simulated annealing algorithm (SA) for various loading conditions, contract participation among generating units and contract violation by the distribution companies.

Time domain simulations are used to study the performance of the power system and control logic. Suitable method for controlling the thermal-thermal power system is described. Analysis reveals that CES unit fitted in either of the areas is as effective as CES units fitted in both the areas and improves the dynamic performances a considerable extent following a load disturbance in either of the areas. Simulation studies carried out on a two-area interconnected power system each containing two units, with and without considering CES units, shows that the proposed control schemes are very effective for the generators taking part in load following.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121086413","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 general the choice of PV array size is calculated using hourly meteorological station data (8760 steps/annum) and daily average input and output to the battery for remote or stand alone PV power plants. In this paper optimal sizing of PV array is carried out for an existing critical load consisting of constant DC load and AC load of intermittent periodic duty with starting nature, connected to single phase Domestic Supply (DS) with Diesel Electric Generator (DEG) as parallel redundant reserve source and an Uninterrupted Power Supply (UPS) in series with critical DC load. Approximate 5 minute solar radiation data (105120 steps/annum) is calculated using one hour meteorological station data and the same is used for studying the energy transactions between various devices and loads in the modified system. A typical critical load of urban roof top Base Transceiver Station (BTS) is considered as load. The optimal size of PV array is calculated for the above mentioned load for a desired Loss of Power Supply Probability (LPSP), minimum OPEX and CAPEX by considering long term performance degrading factors. The aforementioned problem is formulated and Genetic Algorithm (GA) is used to solve the optimization problem. The corresponding results are discussed.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128534853","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}

Everyone demands for reliable and good power quality. There are different problems in power quality like harmonic distortion, flicker, notching, transient, etc. Voltage sag and swell are the major problems in power quality. Dynamic voltage Restorer (DVR) is a custom power device used for mitigation of voltage sag and swell. DVR is connected in series by using the injection transformer to inject the appropriate voltage to mitigate voltage sag/swell and maintain the load voltage constant. For the generation of this compensating voltage there are two steps which are reference voltage generation and gate pulse generation for IGBT's of VSC. In this paper two methods are used for reference voltage generation viz Synchronous Reference Frame (SRF) theory and Fourier transform technique. These methods detect the voltage sag/swell condition and give the reference voltage. Hysteresis controller is used for gate pulse generation in both methods. Simulations are carried out for addition of three phase RL load, removal of load and also for three phase system fault.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115686470","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}
