In recent decade, development of telecommunications infrastructure has led to rapid exchange of data between the distribution network components and the control center in many developed countries. These changes, considering the numerous benefits of the Distributed Generators (DGs), have made more motivations for distribution companies to utilize these kinds of generators more than ever before. ...

Distribution smart grid is very important part of the smart grid. Utilities use Distribution Management System (DMS) as supervisory control layer at the power system control centers. State Estimation (SE) and Volt-Var Control (VVC) are the prime applications of the DMS. In the modern DMS, SE is required for extensive monitoring and control of the entire distribution network. In the presence of ...

Currently, there is a rapid growth in the installation of photovoltaic solar systems power distribution systems. The functionalities smart inverters can bring benefits operational performance network. In this work, influence control functions: fixed factor; Volt-VAr; and Volt-Watt, evaluated voltage regulation network, assuming various operating scenarios. For this, flows are simulated consider...

This paper presents a multiobjective daily voltage and reactive power control (Volt/VAr) in radial distribution systems, including distributed generation units. The main purpose is to determine optimum dispatch schedules for onload tap changer (OLTC) settings at substations, substation-switched capacitors, and feeder-switched capacitors based on the day-ahead load forecast. The objectives are s...

For active distribution networks (ADNs) integrated with massive inverter-based energy resources, it is impractical to maintain the accurate model and deploy measurements at all nodes due large-scale of ADNs. Thus, current models ADNs are usually involving significant errors or even unknown. Moreover, partially observable since only a few available pilot users. To provide practical Volt/Var cont...

The massive penetration of distributed energy resources (DERs) in distribution networks provides a strategic opportunity for the system operator (DSO) to coordinate assets appropriately and offer services transmission systems. IEEE std. 1547-2018 introduced control mechanism enable power electronic converters (PECs) several services, including voltage regulation by controlling reactive injectio...
