As described previously, the distribution grid is becoming highly active with the penetration of DERs and micro-grid connections. The advanced applications in the DMS are facing completely new environments that are not like the traditional passive networks as the basis of the conventional applications and will result in considerable challenges. The most important challenge comes from the bidirectional power flow in the grid, which may change from time to time depending on the real-time dynamics of the load, the DER generation distributions. The second challenge comes from the additional uncertainties associated with DER generation, in which most of the generation may come from intermittent renewable resources. The advanced DMS applications may, thus, need to be sufficiently robust and able to respond quickly to cope with dramatic changes in certain conditions. Some of the key applications may need to be able to look ahead when providing predicted operational schedules and strategies, including IVVC, FDIR, and ONR. The following paragraphs discuss the key features of the typical advanced DMS applications. In the case that a microgrid is involved, advanced distribution management system (ADMS) may also be required to maintain system power quality through balanced frequency and voltages.

An advanced distribution Managements system (ADMS) is software-based that comprises a designed application platform for managing the distribution network to operate optimally. The distribution network operator (DNO) is compared the minimum power loss profile, voltage profile, and maximum energy saving cost for better operation at each node. Therefore, a good distribution system is expected to have a flat Voltage profile at each node, maximum efficiency, maximum cost of saving, and minimum power loss. One of the operations is Volt/var optimization, which aims to minimize power loss and manage reactive power control and Voltage control devices. Therefore, Voltage and reactive power control (Volt/var) is essential for power loss minimization and Voltage profile enhancement. The Volt/var control is new for the distribution management system (DMS) and ADMS automation system.

Modern distribution systems have been monitored, supervised and controlled by the so-called Advanced Distribution Management System (ADMS), which comprises high levels of automation, Advanced Metering Infrastructure (AMI) with two-way communication networks, and processing and control centers [3, 8]. This structure allows implementing a modern VVC, the Integrated Volt/Var Control (IVVC), which enables the integration of controllable equipment in a centralized approach [9].
