“…In particular, an extra active power injection (or absorption) could be requested to simulate the inertial behaviour of synchronous An analysis of the voltage support function through reactive power injections by static generators (in particular photovoltaic) is presented in [31] referring to German grid codes. Focusing on the effects of voltage regulation in LV networks, other results are presented in [32].…”

Abstract:The recent growing diffusion of dispersed generation in low voltage (LV) distribution networks is entailing new rules to make local generators participate in network stability. Consequently, national and international grid codes, which define the connection rules for stability and safety of electrical power systems, have been updated requiring distributed generators and electrical storage systems to supply stabilizing contributions. In this scenario, specific attention to the uncontrolled islanding issue has to be addressed since currently required anti-islanding protection systems, based on relays locally measuring voltage and frequency, could no longer be suitable. In this paper, the effects on the interface protection performance of different LV generators' stabilizing functions are analysed. The study takes into account existing requirements, such as the generators' active power regulation (according to the measured frequency) and reactive power regulation (depending on the local measured voltage). In addition, the paper focuses on other stabilizing features under discussion, derived from the medium voltage (MV) distribution network grid codes or proposed in the literature, such as fast voltage support (FVS) and inertia emulation. Stabilizing functions have been reproduced in the DIgSILENT PowerFactory 2016 software environment, making use of its native programming language. Later, they are tested both alone and together, aiming to obtain a comprehensive analysis on their impact on the anti-islanding protection effectiveness. Through dynamic simulations in several network scenarios the paper demonstrates the detrimental impact that such stabilizing regulations may have on loss-of-main protection effectiveness, leading to an increased risk of unintentional islanding.

“…When the voltage drops between 50% and 90%, the PV grid-connected system needs to have the linear output reactive current. When the voltage drop depth of the grid is less than 50%, 100% reactive current is required to provide [1][2].…”

“…However, new grid code are starting to permit the PV units to remain connected to the grid and even actively support the grid during faults and transients [35]. For example, due to the significant penetration of solar sources in the German power grid, the German grid code which is sufficiently developed on PV sources, has renewed requests for PV sources connected to the grid.…”

Electric Vehicle (EV) technology is expected to take a major share in the light-vehicle market in the coming decades. Charging of EVs will put an extra burden on the distribution grid and in some cases adjustments will need to be made. On the other hand, EVs have the potential to support the grid under various conditions. This paper studies possible potential and applications of Vehicle to Grid (V2G) services, including active power services, which discharge the EV batteries, and power quality services, which do not engage the battery or require only small amounts of battery charge. The advantages and disadvantages of each service and the likelihood that a given service will be effective and beneficial for the grid in the future are discussed. Further, the infrastructure cost, duration, and value of V2G services are compared qualitatively.
