Energy storage regulates reactive power
The distribution system used in this study is a real medium voltage, 13.8-kV urban feeder, located in the city of Belo Horizonte, Minas Gerais State. This feeder supplies Mineirão Stadium and part of the Federal University of Minas Gerais, having an average load of 2.6 MVA with the peak load reaching 6 MVA. An. . The data for the load curves were obtained from measurement units shown in Fig. 1. These data refer to apparent power measurements. . To assess the influence of BESS reactive power control, three different techniques are evaluated: power factor control, volt–VAR control and power factor correction. . The active power control of the photovoltaic plant in Mineirão stadium, as many others, consists of injecting all the available watts into the grid since it is a commercial plant. Figure. The aim of the analysis is to validate the use of active and reactive power injection provided by BESS in controlling the feeder losses and voltage profile. The methodology consists of analyzing typical load curves obtained from feeder measurement data and carrying out simulations considering the BESS injections. [pdf]
FAQS about Energy storage regulates reactive power
Do outer loop active and reactive power controllers ensure battery energy storage system performance?
Abstract: This paper proposes outer loop active and reactive power controllers to ensure battery energy storage system (BESS) performance when connected to a network that exhibits low short circuit ratio. Inner loops control the BESS current components.
What are the main energy storage functionalities?
In addition, the main energy storage functionalities such as energy time-shift, quick energy injection and quick energy extraction are expected to make a large contribution to security of power supplies, power quality and minimization of direct costs and environmental costs ( Zakeri and Syri 2015 ).
Does reactive power control affect a distribution feeder?
One way to mitigate such effects is using battery energy storage systems (BESSs), whose technology is experiencing rapid development. In this context, this work studies the influence that the reactive power control dispatched from BESS can have on a real distribution feeder considering its original configuration as well as a load transfer scenario.
What is reactive power control?
The reactive power control is part of CEI 0-16 and CEI 0-21, Italian standards defining the rules of connection of active and passive users to the grid ( Delfanti et al., 2015 ).
How does a battery energy storage system work?
3.1. Battery Energy Storage System The BESS consists of an active front end (AFE), with a 30 kV A nominal power, connected to the grid and to a DC low voltage bus-bar at 600 V through a DC link supplied by a 20 kW DC/DC buck booster and a Li-Polymer battery with 70 A h and 16 kW h total capacity.
What is active power control?
The active power control performs a peak shaving logic that has been already tested and explained by the authors in Sbordone et al. (2015). The monitoring and control system read the active and the reactive power in the measurement point.
