Impact of distributed generation and energy storage systems on electrical power distribution systems

Abstract

Worldwide is the concern about climate change and the impact on our planet indisputable. One of the aspects that enhances environmental problems is the generation of energy through conventional methods. Due to this, governments all over the world, and particularly Ecuador, opted for the implementation of renewable energy for the generation of electricity. This paper discusses possible technical impacts of distributed generation and energy storage of local distribution networks in Ecuador. Technical impacts on losses, voltages and reversed power flow are analyzed. OpenDSS software was used to model the networks. Different scenarios of photovoltaic (PV) penetration were analyzed. Also, the effect of the incorporation of storage in a high PV penetration network was examined.
