Aggregated effect of price-taking users equipped with emerging demand-side technologies on performance of future grids

摘要

The increased penetration of intermittent renewable energy sources (RESs) requires flexible resources such as demand response (DR) and energy storage to achieve balance between demand and supply in future grids (FGs). Hence, it is necessary to consider the impact of emerging demand-side technologies for modelling net demand in FG Scenarios. This paper studies the aggregated effect of PRICE-TAKING USERS equipped with such technologies on the performance of FGs. For such a study, a GENERIC demand model is developed, which captures the essential behaviour of those users at higher voltage levels. The demand model, inspired by the smart home concept, is formulated as an optimisation problem aiming to minimise the electricity cost. To showcase the performance of the model, we study the effect of price-taking users equipped with rooftop photovoltaic (PV)-battery systems on the load profile, balancing and loadability of the Australian National Electricity Market with an increased penetration of RESs.
