Until today, there are more than 112 GW installed photovoltaic and wind parks in Germany and around 90\% of the installed renewable generators are integrated into distribution networks. As a result, distribution networks are often facing congestion problems and more investments are needed for the required network development plans. The political decisions in Germany for increasing the share of renewables in electricity consumption up to 65\% until 2030 and the nuclear phase out until 2022 and further shutdowns of the coal power plants raised serious concerns about the reliability of power supply and feasibility of the transition plan. The present dissertation has a look over the recent developments and offers a methodology for reduction of the resulted costs from further integration of renewable generators into the distribution networks. The suggested methodology is based on a cellular approach and helps also to postpone the unnecessary costly network expansions. Furthermore, it helps to integrate the renewable generators in an optimized way which has an added value to move towards the defined sustainability goals. The proposed methodology has two steps. The first step is made up of the cellular approach and grey wolf optimization in MATLAB environment. In this step, the optimal combination of technologies for fulfillment of the defined goals are found out. The second step consists of the quasi dynamic simulations in PowerFactory environment. In this step, the suggested results from MATLAB optimization are investigated in semi-real situations. With the quasidynamic simulations, it is checked whether the results are tolerable from the point of view of network operation and whether it is possible to facilitate the network operation with certain strategies.}, subject = {Cellular approach; Optimization; Renewable energy; Generation; Distribution networks; Zellularer Ansatz; Optimierung; Erneuerbare Energien; Erzeugung; Verteilnetze; Verteilungsnetz; Erneuerbare Energien; Elektrizit{\"a}tserzeugung; {\"U}bertragungsnetz; Netzstabilit{\"a}t (Elektrische Energietechnik)}, language = {en} }
