Feasibility study for the integration of a microgrid in a residential building

Abstract

This project proposes a hybrid energy system between conventional generation from the public electrical network and renewable generation for a residence building located in Quito on Amazonas and United Nations Avenue. The study demonstrates its technical and economic feasibility. The system was modelled through the hybrid optimization software Homer Pro, specifying in the optimization of hybrid systems where the model demonstrated that the system has the capacity to satisfy the energy demand of the building in an efficient and reliable way, having benefits such as an economic savings by reducing energy costs in the long term, in addition to sustainable development, being able to reduce dependence on fossil fuels, and being friendly to the environment, without emitting greenhouse gases, being a viable and sustainable solution for electrifications in residential buildings in Quito. For the system, the available resources were used to the maximum, taking advantage of the space on the building's terrace for the installation of photovoltaic panels. In addition, a gas-fired electric generator with cogeneration of heat and power (CHP) was installed, which makes it possible to take advantage of the residual heat of the process to provide hot water for sanitary use to the building, which results in greater cost and energy savings.
