119 Planning of Synchronous Distributed Generation Considering Voltage Profile Imbalance and Dip Ahmadreza Eslami a eslami@ec iut ac ir Date of Submission 2014 10 3 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Mohammad Esmaeil Hamedani Golshan h golshan@cc iut ac irAbstract Nowadays the need for optimum energy consumption and decreasing environmentaleffect of electricity resources along with increase of customer demand for high powerquality and reliability have led power companies to the use of distributed generation Growing penetration level of distributed generation in power system can affect powerquality considerably Therefore firstly to prevent undesirable effects that these sourcesmight have on the system and second to employ their potentials in improving powerquality it seems necessary to consider power quality phenomena in planning and operationof distributed generation Synchronous generators are widely used as distributedgeneration in Iran With respect to this fact planning of distributed synchronous generatorswith regard to improvement in some power quality phenomena has been taken as thepurpose of this thesis Phenomena under investigation are mainly high frequent voltagephenomena including steady state voltage profile voltage imbalance and Voltage dip Inthe first step proper indices are introduced for every phenomena and from voltage qualitypoint of view multi objective system performance index is proposed Voltage profile andimbalance indices are introduced based on voltage sequence component in system buses Evaluation of voltage dip has been accomplished based on monte carlo stochasticsimulation and the proposed indices for dip consider factors like voltage dip magnitude number and the number of sensitive load interruption due to voltage dip Through differentscenarios distributed generation installation planning with regard to different powerquality phenomena is evaluated and optimal capacity and location of distributedsynchronous generators will be determined Systems under investigation in this study areIEEE 13 bus test feeder distribution level of IEEE 30 bus system and IEEE 34 bus testfeeder By use of proper load flow algorithms and short circuit analysis optimal planningof distributed synchronous generators is performed for these systems Simulations areimplemented in MATLAB software Keywords Distributed Generation Distributed Synchronous Generators Power Quality Voltage Quality Planning of Distributed Generation Multiobjective Index
