“…Design, control, protection [16,17], security [18], operation status (grid-connected or/and island mode), and energy management [19] are the main areas of the MG field. The LAMBDA MG LAB consists of several sources: a 12 kW three phase PV system (PV1), a single-phase PV system (PV2) with 2 kW rated power, an emergency generator set (EGS) with 5.2 kW installed for island mode, a battery energy storage system (BESS) with 6.5 kWh of rated capacity (2.2 kW charge, 1.8 kW of AC discharge), and an uninterruptible power supply (UPS) to supply the electronic components [20].…”

Currently, despite the use of renewable energy sources (RESs), distribution networks are facing problems, such as complexity and low productivity. Emerging microgrids (MGs) with RESs based on supervisory control and data acquisition (SCADA) are an effective solution to control, manage, and finally deal with these challenges. The development and success of MGs is highly dependent on the use of power electronic interfaces. The use of these interfaces is directly related to the progress of SCADA systems and communication infrastructures. The use of SCADA systems for the control and operation of MGs and active distribution networks promotes productivity and efficiency. This paper presents a real MG case study called the LAMBDA MG testbed laboratory, which has been implemented in the electrical department of the Sapienza University of Rome with a centralized energy management system (CEMS). The real-time results of the SCADA system show that a CEMS can create proper energy balance in a LAMBDA MG testbed and, consequently, minimize the exchange power of the LAMBDA MG and main grid.

Penetration of distributed energy resources (DERs) such as wind, solar and battery units are rapidly increasing in distribution power system (DPS). In view of power grid reliability and efficiency, cyber and physical secure of these units are highly important since it can directly impact power system operations. This paper investigates the dynamic behavior of power distribution during cyber, physical and natural strikes on reactive power control in DER units. Various fault scenarios including modifications in voltage-reactive power (Volt-Var) curve pattern such as slope of the curve, dead band; and changes in capacitive or/and inductive reactive power delivery to the power grid are presented. Further, fault scenarios are investigated with the presence of dynamic VAR (volt-ampere reactive) compensation (DVC) units in the system. A southern California 140-bus commercial distribution power system is selected as a test system and faults are analyzed in both Matlab/Simulink and ETAP simulation platforms. The results evidence that the modifications in reactive power control values at DER units significantly affects the voltage quality/security of the system and affect the number of switching actions of voltage regulators (VRs). In contrast, DPS connected with DVCs improves voltage quality and reduces the number of switching actions of VRs, also voltage quality/security is maintained during the faults.

“…In [9] a MiTM is demonstrated on a distribution reactive power compensation system by exploiting vulnerabilities in the Modbus protocol which is used to communicate measurement information to the compensation control system. Several attacks on measurement devices and solar PV inverters are demonstrated using a simulation platform in [10]. An optimal Volt-VAr optimisation system is proposed in [11], with capability of False Data Injection Attacks (FDIA) mitigation.…”

Rapid modernisation of distribution power systems aims to improve system efficiency and reliability while increasing photovoltaic (PV) penetration levels. However, ensuring the cyber security of such smart distribution grids has emerged as major challenge. Cyber-attacks on key equipment of distribution power systems may lead to inefficient operation of the grid, breach private smart meter data or cause intentional false tripping of feeders. In this paper, a man in the middle attack on a commercial solar PV inverter, which provides ancillary services to the grid, is demonstrated to cause an intentional false tripping of the entire feeder leading to a regional blackout. The successful experimental implementation of the attack reveals the effectiveness and the risk of this attack. Detailed risk analysis is conducted to asses the influence of different factors, such as feeder loading and PV inverter capacity, on the effectiveness of the proposed attack. Index Terms-Cyber-physical attack, man in the middle attack, solar PV inverter, smart grid.
