The flexible operation modes of microgrid result in an extreme challenge for the protection and control of microgrid. Therefore, this paper proposed a centralized protection and control scheme for microgrid. To identify the faulted region conveniently, the microgrid is divided into several zones in advance. Intelligent circuit breakers communicate with each other, then send real-time information by...
The correlation among wind velocity, light intensity and load is not considered in generation capacity configuration in microgrid. This paper proposes a combined sampling method which can consider the correlation based on Copula theory. It analyzes the law of data, then chooses the best Copula function of every segment to sample and combines all sampling result together. A mathematical model of capacity...
As is well known, the anti-peaking characteristic of wind generation leads to evident curtailments of wind farms. With high energy density and flexible installation position, the battery energy storage system (BESS) can provide a new routine to relax the bottleneck of the peak-load regulation, conducive to the absorption of wind power and the economy of system operation. Therefore, with taking account...
With raising penetration of distributed generations (DGs), it is of great demand for accurate short-circuit current calculation which is the foundation of planning, operation and relay protection of power systems. When distribution networks are integrated with increasingly number of DGs, short-circuit current calculation becomes less convenient because the dimension of nodal admittance Y matrix expands...
Power system components are susceptible to failures that could result in island formation which is highly undesirable and should be avoided. For a safe and reliable power system operation, all insecure operating states such as critical nodes and sets of candidate transmission links that could cause cascading outages within the networks must be quickly detected and identified in advance. This paper,...
The frequent incident of voltage collapse in the modern power system due to incessant increase in load demand has posed a great challenge to power system utilities. This paper demonstrates the concept of inherent structural characteristics and the traditional approach of voltage collapse proximity index (VCPI) in predicting the collapse point in the power system network. The conventional technique...
