Energilagring med batterier och vätgas. Energilagring är ett sätt att lagra energi till dess den behöver användas. Det kan handla om att lagra när elen är billig och använda när den är dyr, eller att balansera kraftsystemet när väderberoende energislag inte kan producera el. Batterier och vätgas är två typer av energilager som är intressanta för det svenska kraftsystemet.
Distributed generators are playing a vital role in supporting the grid in ever-increasing energy demands. Grid code regulation must be followed when integrating the photovoltaic inverter system to the grid. The paper investigates and analyzes a controller model for grid-connected PV inverters to inject sinusoidal current to the grid with minimum distortion. …

This paper surveys current literature on modeling methods, control techniques, protection schemes, applications, and real-world implementations pertaining to grid forming inverters (GFMIs).
remedies cannot be applied for grid-following inverters. In fact, the DC link of grid-forming inverters is connected to a stiff DC source; and then, the DC link voltage control is not an issue for this kind of inverters. This paper is organized as follows. Section II reviews the variety of approaches available in the literature for the control ...

In this paper, different control approaches for grid-forming inverters are discussed and compared with the grid-forming properties of synchronous machines. Grid-forming inverters are able to operate AC grids with or without rotating machines. In the past, they have been successfully deployed in inverter dominated island grids or in uninterruptable power …

A Review of Control Techniques and Energy Storage for Inverter-Based Dynamic Voltage Restorer in Grid-Integrated Renewable Sources
This article proposes a grid-following inverter control scheme using an interconnected generalized integrator and fuzzy PID dc-bus voltage controller (FPID-IGI) in photovoltaic (PV) applications. The proposed FPID-IGI controller is designed to extract the maximum power from the PV system to the local loads with a unity power factor (UPF) with …
Energilagring för elektricitet kan göras genom flera olika tekniker och på varierande skala. Storskaliga energilager kan lagra energi över perioder på flera timmar till månader och ansluts på region- eller stamnätsnivå. Idag finns mycket lite storskalig energilagring i Sverige, huvudsakligen till följd av ett lågt behov.
