Development of Reliability Contribution Function of Power System including Wind Turbine Generators combined with Battery Energy Storage System

Abstract

-This paper presents a study on reliability assessment and new contribution function development of power system including Wind Turbine Generator(WTG) combined with Battery Energy Storage System(BESS). This paper develops and proposes new reliability contribution function of BESS installed at wind farms. The methodology of reliability assessment, using Monte Carlo Simulation(MCS) method to simulate sample state duration, is proposed in detail. Forced Outage Rate(FOR) considered probabilistic approach for conventional generators is modelled in this paper. The penetration of large wind power can make risk to power system adequacy, quality and stability. Although the fluctuation of wind power, BESS installed at wind farms may smooth the wind power fluctuation. Using small size system as similar as Jeju island power system, a case study of reliability evaluation and new proposed contribution function of power system containing WTG combined with BESS is demonstrated in this paper, which would contributes to BESS reliability contribution and assessment tools of actual power system in future. 본 논문에서는 출력변동성이 큰 풍력발전기가 증가함에 따라

Reliability evaluation of power system considering wind generators coordinated with multi‐energy storage systems

“…5 shows the conventional model, and Fig. 6 shows the new proposed model for the power system including multi‐WTG and multi‐ESS in this paper [1, 18, 19].…”

Adequacy analysis of electric power systems with wind and solar power stations

“…, in [15]. We can consider an optimal solution of the problem (6) - (12) as equally probable for every hour. The problem (6) -(12) has a solution because its feasible set is not empty (the point 0 , is followed from theorems [10].…”

“…Scientific researches of adequacy analysis of electric power systems with wind power generators and different storage batteries are presented in articles [9][10][11][12][13][14][15][16][17][18][19]. However, we concentrate our attention on a research of R. Billinton [13][14][15] and Y-F. Li [9][10][11]16].…”

“…Integration of wind power stations and storage batteries in the system along with detailed describing of adequacy analysis is considered in these articles. We also give high estimation of research of Ungjin Oh [12]. Ungjin Oh fully described of charge and discharge processes of storage batteries under solving of the problem of adequacy analysis of electric power system with wind power plants and energy storages.…”

Stability improvement of 200 MW Gabal El-Zayt wind farm connected to electrical grid using supercapacitor and static synchronous compensator during extreme gust

“…Batteries and supercapacitor (SC) are types of ESS that have higher speed response than other traditional ESS that has mechanical parts [9,10]. In [11,12] batteries are used with wind energy to improve response and stability. In [13] batteries are used with wind energy using fuzzy logic control.…”
