Demand Side Flexibility Prospects In Modern Lv Networks: A Probabilistic Assessment

Modern and flexible schemes facilitating higher penetration of residential distributed energy resources (DERs), such as photovoltaics, wind generators, electric heat pumps and electric vehicles in low voltage (LV) networks are of high interest in recent years. This paper investigates multiple simplified demand side flexibility (DSF) schemes to achieve said goal, while considering uncertainties that are related to the stochastic behaviour of the various network components and DERs. A probabilistic assessment methodology is adopted based on the Monte Carlo simulation, whilst real LV feeders and DER profiles were used to measure the performance of the investigated DSF schemes. The results include a probabilistic assessment for the technical performance of each DSF scheme by means of power delivery, operational improvement in higher penetration levels of residential DERs, and a thorough comparison of the effectiveness between these DSF schemes.
