“…Volt / Var control determines the best control action to maintain the voltage profile within a desired range and minimizing system losses controlling the reactive power flow in the distribution system [4]. This function provides the operator with the best actions and recommendations to maintain the high quality voltage profile minimizing the losses and the reactive power demands.…”

Abstract-The integration of significant volumes of distributed and renewable energy resources directly connected to the distribution network raises new requirement to maintain and operate the power system in secure state. Thus the Distribution Management System (DMS) needs to be updated and integrated with new functionality to provide effective support for the operators. The DMS is a control center solution that provides the needed functionality for the management of medium and low voltage distribution networks. This paper aims to provide an overview of the main functions present in today´s DMS platforms and to identify the new requirements to better serve in a smart grid context. Index Terms-active distribution networks, distribution management system, frequency control, smart grid, synthetic inertia.

“…Voltage V h (t), phase angle of the voltage δ V,h (t), active power P h (t) and reactive power Q h (t) are associated to the bus h at time t. In order that voltage variation may not degrade the customer voltage supply quality, feeder voltage should be maintained within the permissible range [20], [21], i.e. :…”

Abstract-The evolution of electrical grids, both in terms of enhanced ICT functionalities to improve efficiency, reliability and economics, as well as the increasing penetration of renewable redistributed energy resources to favor sustainability of the production and distribution of electricity, results in a more sophisticated electrical infrastructure which poses new challenges from several perspectives, including resilience and quality of service analysis. In addition, the presence of interdependencies, which more and more characterize critical infrastructures (including the power sector), exacerbates the need for advanced analysis approaches, to be possibly employed since the early phases of the system design, to identify vulnerabilities and appropriate countermeasures. In this paper, we outline an approach to model and analyze smart grids and discuss the major challenges to be addressed in stochastic model-based analysis to account for the peculiarities of the involved system elements. Representation of dynamic and flexible behavior of generators and loads, as well as representation of the complex ICT control functions required to preserve and/or re-establish electrical equilibrium in presence of changes (both nominal ones, such as variable production by a photovoltaic energy source, and failures/disruptions both at electrical and ICT level) need to be faced to assess suitable indicators of the resilience and quality of service of the smart grid.

“…Many recent projects envisaged the possibility to modulate the energy consumption in LV networks by modulating the feeding voltage of the end-users [1], [2]. This approach, known as CVR (Conservation Voltage Reduction), is suitable for networks with three-phase users, therefore with balanced voltage on the three phases.…”
