This thesis presents an approach to design and implementation of a Renewable Power Complex (RPC) containing several intermittent sources. The purpose of RPC is to improve the poor rural distribution network voltage portfolio which can be traced back to the typical long distance radial lines. With the purpose of improve system overall voltage, iterative studies are conducted to calculate the requirements of RPC in terms of capacity. Afterwards, the proposed approach is verified at a test system. From implementation perspective, the capacity of the inverter interfacing the generation unit is a bottleneck that limits the possible dimension of the RPC. Consequently, the RPC is actually composed by several atomic units with a much smaller scale. The software where the potentials of intermittent generation sources can be estimated given the geographic information is used to optimize the size of RPC atomic units. Finally, the thesis tackles a high level design of automations system under which the RPC is operated. The functionality described are all compliant with commonly accepted IEC 61850 standards with the intention to ease the future implementation.
