The rising significance of renewable energy increases the importance of representing time-
varying input data in energy system optimization studies. Time-series aggregation, which …

Distributed energy resources (DERs) have gained particular attention in the last few years
owing to their rapid deployment in power capacity installation and expansion into …

Distributed energy resources (DERs), such as renewable energy sources (RESs) and
energy storage systems (ESSs), are inevitable parts of future power grids. However, the high …

As power systems evolve by integrating renewable energy sources, distributed generation,
and electric vehicles, the complexity of managing these systems increases. With the …

In this paper, a novel photovoltaic (PV) system planning framework is proposed for
distribution grids. The main contribution of this work is that the volt-var control (VVC) …

High penetration of solar photovoltaic (PV) units in distribution grids and the variability of
their output power have caused new challenges to grid operators. Voltage fluctuations and …

We propose a comprehensive framework for the optimal day-ahead scheduling of power
distribution systems (PDS), based on a mixed-integer linear programming (MILP) model …

The ancillary services are becoming more important due to the increasing integration of non-
dispatchable and intermittent renewable energy sources. Such behavior under deregulation …

In this study, a multi-objective optimization method is proposed to solve day-ahead voltage
control problems in distribution systems. The main purpose is to determine the optimal …

Most conventional voltage control schemes in distribution systems are controlled through the
tap change of the transformer. However, as large-capacity distributed generations (DGs) are …
