A research framework for generalized congestions and market power

Yusheng Xue Tainran Li Xia Yin Zhao Yang Dong Jie Huang

Besides the transmission congestion reflecting the physical stability of a power system,power market is also constrained by factors like primary energy,emissions,technical support and multi-game.These factors affecting both competition level and efficiency of a power market can be called by ageneric term as generalized congestions.The purpose of regulation is to avoid the abuse of market power and reduce the risk in social welfare.However,inappropriate regulation may also degrade the efficiency of a market;even endanger the market and social stability.So regulation is also a kind of generalized congestions.The capability of market participants to influence(increase or decrease)market efficiency through taking the advantage of generalized congestions can be called as market power,while generalized market power reflects the capability to influence social welfare.Generalized congestions,market power and generalized market power are analyzed in aspects such as classification,evaluation indexes,control measures and research methods.A framework is proposed for the mechanism study of generalized congestions,market power and generalized market power.With this framework,experimental economics can be implemented,and comprehensive analysis can be taken to study the mechanism for generalized congestions to influence the market power.

Coherency identification of generators in interconnected power systems with renewables

Institution of Engineering and Technology eBooks (2020)

Zhenzhi Lin Fushuan Wen Yi Ding Yusheng Xue Shengyuan Liu

Identification of coherent generators (CGs) in power systems is one of the key steps in determining controlled islanding strategies. In this chapter, a wide-area measurement system (WAMS) and agglomerative hierarchical clustering (AHC) algorithm-based coherency identification method is presented for interconnected power systems with aggregated renewable sources. First, the trajectories measured by WAMS are transformed to the center of inertia (COI) based ones for better representing the dynamic behavior of a given power system, and ten dissimilarity indexes are presented for determining the similarity between the trajectories of any two generators. Second, a CRITIC (CRiteria Importance Through Intercriteria Correlation)-based method, in which entropy and the Spearman's rank correlation coefficient are integrated for reflecting the differences and correlations among multiple indexes, respectively, is presented to integrate the trajectory dissimilarity indexes. Next, the AHC algorithm is utilized to identify CGs. Finally, a modified New England-New York interconnected power system (NENYPS) with a large number of renewables, a simplified actual Western Interconnection power system (WECCPS) in North America, and the eastern part of Guangdong power system in China with a recorded oscillation event happened are utilized to demonstrate the proposed wide-area coherency identification methodology.

An Evaluating Method for Generation Investment Within an Emission Trading Scheme

Dianli xitong zidonghua (2010)

Yusheng Xue

Generation investment decision-making is a very complicated problem in the electricity market environment due to various kinds of uncertainties. The enforcement of the energy-saving and emission reduction policy as well as the emissions trading scheme will make the problem even more complicated especially for coal-fired generation units. Against such a background,a new approach is developed for evaluating the value of a generation investment project in a power industry environment with the emission trading enforced. A real option based model for this purpose is proposed,and the project value and optimal investment timing obtained by the least-squares Monte-Carlo method. The impact of market factors and the regulating policy on generation investment decision-making are illustrated by a numerical example with different scenarios.

A Comprehensive LVRT Control Strategy for DFIG Wind Turbines With Enhanced Reactive Power Support

IEEE Transactions on Power Systems (2013)

Dongliang Xie Zhao Xu Lihui Yang Jacob Østergaard Yusheng Xue

The paper presents a new control strategy to enhance the ability of reactive power support of a doubly fed induction generator (DFIG) based wind turbine during serious voltage dips. The proposed strategy is an advanced low voltage ride through (LVRT) control scheme, with which a part of the captured wind energy during grid faults is stored temporarily in the rotor's inertia energy and the remaining energy is available to the grid while the DC-link voltage and rotor current are kept below the dangerous levels. After grid fault clearance, the control strategy ensures smooth release of the rotor's excessive inertia energy into the grid. Based on these designs, the DFIG's reactive power capacity on the stator and the grid side converter is handled carefully to satisfy the new grid code requirements strictly. Simulation studies are presented and discussed.

Risk of Jamming Attacks on a Virtual Power Plant with Multiple Distributed Generators

Yan Xu Fushuan Wen Chung‐Li Tseng Ivo Palu Yusheng Xue

Consensus control has recently been employed to regulate active power output of distributed generators (DGs) of a virtual power plant. However, such networked control systems, integrating information and wireless communication technologies, are subject to cyberattacks. This paper investigates the risk of jamming attacks on the coordination of DGs in a distribution network. A binary-valued stochastic process is employed to model packet losses caused by jamming attacks and nonmalicious communication failures. Using an attack rate to characterize the strategy of an attacker, the proposed method highlights the vulnerability of the cooperative control of DGs subject to cyberattacks. Furthermore, a probabilistic instability analysis provides the conditions under which jamming attacks can prevent active power outputs of DGs from reaching a consensus to track a dispatch command. Accordingly, this paper shows how an attacker might launch malicious attacks to impair consensus-based control of DGs so that energy companies can take precautions. Finally, the theoretical results are verified on the IEEE 34-node test feeder under two different attack strategies.

Smart Grid Supporting Energy Security and Environmental Safety

Power System and Clean Energy (2010)

Yusheng Xue

A power system is closely linked to the primary energy and the environment. With the development of the renewable energy, the aggravation of the energy crisis, the severe situation of the environmental safety, the paper describes new challenges faced to the current power system. It is presented that the smart grid is a global frame to cope with these challenges, and that the smart grid is also an important part in the energy defense system and the environment safety system. Finally, it is pointed out that the smart grid should be read as the vision power system by exploring its essential connotation.
