The influence of different storage technologies on large power system frequency response

Abstract

Abstract-This paper investigates the contribution of energy storage systems to the system frequency response in a large meshed transmission system. The case studies compare the contribution of two types of energy storage technologies, i.e., battery energy storage system (BESS) and flywheel energy storage system (FES), to improve frequency response in the test network. Case studies examine the effect of different type of disturbance on frequency response in the presence of each type of storage technology. The effect of one bulk energy storage and distributed energy storage systems of the same capacity on frequency response of the power system is also investigated.

Identification of Critical Parameters Affecting Voltage and Angular Stability Considering Load-Renewable Generation Correlations

“…The MC simulation requires a certain number of repeated random sampling of uncertain data in order to represent the stochastic behaviour of system parameters. The following equation (11) determines the required Monte Carlo run [43].…”

“…In (11), ɛ is the sample mean error, −1 (•) is the inverse Gaussian conditional probability distribution with a zero mean value and a one standard deviation value, 2 (•) is the variance of a sample, is the required confidence level, and ̅ is the mean of the samples.…”

(Email: buyang.qi@manchester.ac.uk, kazi.hasan@manchester.ac.uk, jovica.milanovic @manchester.ac.uk) is getting steadily adopted by researchers to be applied to all types of stability studies [1,[5][6][7][8][9][10][11][12]. The Monte Carlo (MC) simulations are commonly used to perform these probabilistic studies [5,[13][14][15][16].…”

Impact of inertia emulation control of grid-scale BESS on power system frequency response

“…Also, the steady-state values for the frequency are reached to higher values when Hsyn is increased. Similar analysis is carried by [2], showing the same results, however, no synthetic inertial response is implemented to show the dynamic behavior of the frequency stability of the system. This paper shows the system frequency response for different inertial response and how it reacts with BESS.…”

“…Control strategies, such as Maximum Power Point Tracking (MPPT) and inertial emulation techniques, use ESS, mainly BESS. The influence of different ESS, specifically BESS and flywheels, on large power system frequency responses were studied by [2]. In another paper, [3] develops two control strategies, Coordinated Constant Droop Control (CCDC) and Coordinated Adoptive Droop Control (CADC), to emulate the grid inertial response with the aid of BESS and Flywheels.…”
