Perspectives on Distribution Network Flexible and Curtailable Resource Activation and Needs Assessment

A curtailable and flexible resource activation framework for solving distribution network (DN) voltage thermal congestions is used to quantify three important aspects with respect modelling low networks. This utilizes the states in absence of such or resources as input calculating flexibility signal (FAS). The FAS has some similarities optimal power flow duals associated balance constraint. due drooping design, incentivize corrective prior any limit violations. nonlinear dispatch (RDOPF) resources. Solving OPF problem a large system computationally intensive, second-order cone (SOC) relaxation often applied literature. First, we highlight multi-objective nature SOC relaxed RDOPF. Pareto front tuning mechanism proposed choosing loss penalty factor while reducing optimality gap Secondly, present methodology evaluating temporal locational needs assessment DN, which DSO's can utilize planning operational timescales procurement market. Lastly, impact reactive DN varying load factors. Numerical simulations indicate that presence reduces active by 50% test feeder 0.8 aggregated factor.
