Abstract
Maintaining the stability of the electrical grid becomes more challenging every year. The rapid growth of renewable energy sources (RES) is one of the key reasons. The residential sector is also a large contributor to the destabilisation of the electrical grid due to daily changes in demand. Domestic load is one of the most significant factors in creating peak demands, especially residential space conditioning and water heating. One of the possible solutions to minimise the problem is the usage of hydronic cooling and heating. This paper will present the results of the analysis of the impact of replacing conventional air conditioning and electric water heating with a hydronic system with a heat pump and smart control reacting to grid conditions on the load generated by a typical Queensland household. The study was conducted using measured air conditioning (AC) electrical load and hot water consumption, and wholesale electricity price as an indicator of grid conditions. A series of TRNSYS simulations conducted in this study revealed that hydronic systems could not only decrease the household’s energy consumption but also positively impact the grid by shifting most of the water heating and air conditioning load to periods of overgeneration.
