With the development of smart grid technology, FACTS devices, such as SVC and STATCOM, are widely applied in practice. Since the FACTS devices possess fast dynamic response characteristics, they can provide effective support to power systems stability even during the transient process after severe contingencies. It is helpful to take into account the transient process stability constraints into reactive...
This paper proposes a new and practical model to achieve the electricity market equilibrium based on Linear Supply Function Equilibrium (LSFE) model. In the proposed model, the transmission constraint in addition to the generation constraint and the consumers bidding behavior are considered. The coevolutionary computational approach is proposed to solve the market equilibrium problem. Several cases...
Cascading failures or high-order contingency events result in large blackouts. The causes and analysis of cascading failures in power systems are reviewed in this paper. This paper also discusses the challenges and emerging methods of analyzing cascading failures or higher-order contingencies. A comparison between the methods is presented.
Wind speed forecasting is essential to wind power generation and operation. To improve the performance of wind speed forecasting, analyzing the characteristics of the wind speed time series is necessary, comprehensively, since wind speed change is irregular and may fluctuate violently. In this study, using the technique of the GARCH model kurtosis analysis, the leptokurtosis of wind speed is discussed,...
Distributed energy resources (DE) or distributed generators (DG) with power electronics interfaces and logic control using local measurements are capable of providing reactive power related ancillary system services. In particular, local voltage regulation has drawn much attention in regards to power system reliability and voltage stability, especially from past major cascading outages. This paper...
This paper first briefly reviews the typical functionality and structure of market-based generation and transmission planning tools. Possible new functions are discussed to include bidding strategy models and system dynamics models. The former is used to reflect the behavior and the learning process of market participants and the latter represents an information feedback loop to account for long term...
Large blackouts are typically caused by cascading failure propagating through a power system by means of a variety of processes. Because of the wide range of time scales, multiple interacting processes, and the huge number of possible interactions, the simulation and analysis of cascading blackouts is extremely complicated. This paper defines cascading failure for blackouts and gives an initial review...
