“…Actually, these generators could be coupled with additional compensators to regulate the voltage in its limits [22]. Static compensators (STATCOM), D-STATCOM, static VAR compensators (SVC), fixed capacitor banks and shunt capacitor banks have been investigated in [23]- [26], although some of these devices are costly.…”

Planning, operation and control of active distribution grids by increasing the number of dispersed generators is becoming more important but also more complex. Hence, the importance of controlling the voltage is highlighted in many research papers. Traditionally, in passive distribution networks the voltage rise has been mitigated by network reinforcement. Nowadays, local voltage control, coordinated voltage control and centralized voltage control have been discussed for active networks in research papers. Although all the approaches have been proven to solve the problem of voltage rise in distribution grids, using plenty of sensors to gather huge number of measurement could cause complexity. This paper represents a literature review of different voltage control approaches in active distribution grids and proposes a new procedure to set up a local voltage control law devoted to properly manage the voltage profile (e.g. minimizing losses on MV feeders).

“…DG injections cause voltage rise in the MV feeders, PFC could control the system's voltage by increasing the HC of the distribution grid. In [42]- [45], Static compensators (STATCOM), D-STATCOM, static VAR compensators (SVC), fixed capacitor banks and shunt capacitor banks have been investigated as generator compensators to regulate the voltage. Four different local control schemes are discussed in [46]- [48].…”

The rapid growth of distributed energy resources exploitation can cause voltage violations and overloading on distribution grids due to the uncontrolled and unprogrammable power injections associated with dispersed generators. To overcome these issues, distributed system operators have to evaluate the maximum generation that can be hosted by distribution grids without violating the technical constraints and find the ways to increase it. In this paper, different hosting capacity analyses for different case studies have been reviewed, and a novel model to evaluate hosting capacity in case of grid parameters uncertainties and multi-generator connection is proposed.

“…In fact, these generators could be coupled with additional compensators to increase their capability [19]. Static compensators (STATCOM), Distribution STATCOM (D-STATCOM), Static Var Compensators (SVC), fixed capacitor banks and shunt capacitor banks have been investigated in [20][21][22], although some of these devices are costly. In its most general form, Local Control consists of acting on the power factor of the DG unit in order to keep the voltage at the DG terminals in check.…”

Renewable Energy Sources are becoming widely spread, as they are sustainable and low-carbon emission. They are mostly penetrating the MV Distribution Networks as Distributed Generators, which has determined the evolution of the networks’ control and supervision systems, from almost a complete lack to becoming fully centralized. This paper proposes innovative voltage control architectures for the distribution networks, tailored for different development levels of the control and supervision systems encountered in real life: a Coordinated Control for networks with basic development, and an optimization-based Centralized Control for networks with fully articulated systems. The Centralized Control fits the requirements of the network: the challenging harmonization of the generator’s capability curves with the regulatory framework, and modelling of the discrete control of the On-Load Tap Changer transformer. A realistic network is used for tests and comparisons with the Local Strategy currently specified by regulations. The proposed Coordinated Control gives much better results with respect to the Local Strategy, in terms of loss minimization and voltage violations mitigation, and can be used for networks with poorly developed supervision and control systems, while Centralized Control proves the best solution, but can be applied only in fully supervised and controlled networks.
