Nigeria microgrid control

Six new microgrids have been developed simultaneously in Nigeria as part of a rural electrification program backed by the World Bank. The projects show the considerable possibilities available from the scaling up of microgrid rollout programs. . Microgrids provide resilience, sustainability, and efficient energy solutions by leveraging onsite renewable generation with smart grid resources for better connectivity, decarbonisation, and access to energy. Currently, Nigeria power system is confronted with inadequate generation, outdated generation infrastructur, poor maintenance culture, high network losses and poor tariff [1], [2]. This resulted in an unreliable electric. . Through the installation of this microgrid at Cummins' head ofice in Lagos, Nigeria, Cummins is working forwards its PLANET 2050 goal of a 50% reduction in absolute greenhouse gas emissions from its facilities and operations by 2030.
