Abstract

Integrating renewable energy resources with dedicated energy storage systems in building regimes is becoming viable with numerous well-documented advantages. Multiple buildings, i.e., primary building(s) (with solar & storage) and secondary building(s) (ordinary building dependent entirely on the grid), have bilateral contracts with each other, resulting in an optimized exchange bilaterally and with the grid to reduce grid costs. Further, the allowance of electric vehicles (EVs) in these buildings enable added options to optimize the power flows, focusing on cost reduction. In this work, a mixed-integer linear program (MILP) is formulated to maximize the primary building's profits, along with the financial gains to secondary buildings and a fleet of EVs. The charging infrastructure at the primary building also facilitates the EVs' load by accounting for factors such as feeder time-of-use (TOU) tariffs, contracted rates between the buildings, and EV charging prices. Results for actual load profiles for buildings in Auckland, New Zealand show that primary buildings earn up to 87 % of daily profits along with the 10–41 % daily cost savings for secondary buildings. The insights presented in this work can benefit local aggregators with options to maximize local profits lowering the grid dependence.
