Multi objective Planning of Renewable Distributed Generation and Reactive Resources in Distribution Networks Yasaman Niazi y niazi@ec iut ac ir June 18 2019 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr Mohammad Esmail Hamedani Golshan hgolshan@cc iut ac ir Abstract With increasing the penetration of distributed generation DG especially renewable resources as one of the main re quirements of smart grid development the planning of these resources is of great importance The aim of DG planning is todetermine the location and capacity of these resources in a specified time horizon It is achieved based on an optimizationproblem taking into account different techno economic objectives and constraints Furthermore it can be integrated withthe planning of reactive power resources RPRs which consist of determining the optimal contribution of these resources The joint planning of DGs and RPRs can improve their benefits for distribution networks as well as for DG owners DGOs In this research a novel methodology is proposed for the integrated planning of renewable DGs including biomass solar and wind power and reactive power resources in the distribution system The planning problem is solved from theperspectives of both DG owner and distribution network operator DNO From the perspective of DNO some indicessuch as annual energy losses voltage stability margin supply adequacy of microgrids and the exchanged power with theupstream network are considered as the objective functions Furthermore different constraints of the planning probleminclude active reactive power balance limitation of network voltages the maximum capability of DGs and RPRs and themaximum penetration of DG units are incorporated In each case related to a specific index as the objective function theimpact of planning problem on the other indices is evaluated Also based on the economic parameters two problems ofDG planning are defined with the aim of maximizing the profit from the installation of DGs for the DGOs and DNO Theobjectives of the distribution company and the DG owners will not necessarily coincide and a trade off may be required Therefore the planning problem is converted into a multi objective optimization problem To solve the multi objectiveoptimization problem the epsilon constraint method is used and the Pareto optimal solutions are attained Hence a furtherdegree of freedom is provided for the decision maker to select the final solution The performance of the proposed planningframework is evaluated using detailed simulations on 69 bus PG E distribution system The simulations are performed byGAMS software The simulation results showed that the proposed integrated planning of DGs and RPRs improves differenttechnical indices of the distribution system In addition in many cases optimizing an objective function improves the otherindices to a great extent Furthermore the economic benefits of both DNO and DGOs are increased with the proposedmethod Key Words Planning of distributed generation Renewable distributed generation Economic anal ysis Multi objective decision making
