This work analyses capability of energy storage system (ESS) and demand response (DR) to maximize the hosting capacity (HC) of solar photovoltaic (PV) in distribution network. The optimization model aims to maximize total capacity of PV that can be installed in the distribution system. Three different cases are framed and impact of proposed approach on technical parameters of distribution system such as energy losses, voltage phenomenon and grid peak demand are discussed. In addition, a sensitivity analysis to investigate impact of changing DR participation rate, energy, and power rating of ESS on HC is presented. The effectiveness of ESS and DR in improving HC is simulated on IEEE-33 bus system. Results indicate that jointly coordinating ESS and DR gives higher HC as compared to scheduling ESS or DR alone.
