| Abstract |
This paper presents the design and implementation of a Smart Grid Configuration Tool (SGCT) for Hybrid Electrical Energy Systems (HEES), such as residential, large urban buildings, or smart city districts, equipped with mains, local batteries and renewable energy systems. Batteries charge using electricity generated from renewables or from mains, when utility rates are low, and powers the building when the electricity cost from utility is higher or in case of emergency backup. The developed tool optimizes the cost of energy and the battery lifetime, and provides long term predictions (up to 14 days) of the loads energy utilization in terms of expected input from the Grid, battery reservoir utilization, health and state of charge, load requirements and PV production/utilization, with tunable horizon. |
