The impact of integrating large-scale solar photovoltaic (PV) generation on the balancing requirements in terms of regulation and load-following requirements in the southern Nevada balancing area is evaluated. The “swinging door” algorithm and the “probability box” method developed by Pacific Northwest National Laboratory (PNNL) were used to quantify the impact of large PV generation on the balancing...
The increasing uncertainty caused by a higher penetration level of renewable energy points to the need for sufficient balancing services to ensure secure operation. It is thus necessary to quantify these services accurately and evaluate the cycling and movement of conventional generators that provide load following and regulation services for optimal planning and scheduling of multiple resources....
Contemporary power systems face uncertainties coming from multiple sources, including forecast errors of load, wind and solar generation, uninstructed deviation and forced outage of traditional generators, and unscheduled loss of transmission lines. With increasing amounts of wind and solar generation being integrated into the system, these uncertainties have been growing significantly. It is critically...
The impact of integrating 20% of renewable resources, primarily wind and solar, on regulation and load following requirements within the California Independent System Operator (CAISO)'s Balancing Authority Area is analyzed in detail. The analysis entails a stochastic process that employs Monte Carlo simulations and uses a random number generator to generate forecast errors over multiple iterations...
As the rapid development of Internet technology and the deployment of Internet multimedia applications, it's urgent to solve the QoS problems of the real-time multimedia services in the network for clients. This paper proposes a real-time video stream key frame identification algorithm for QoS, named RVKI. In this algorithm, the frame type of IP packets could be identified at the real-time multimedia...
In the application layer of ad hoc network, a location based video source switching algorithm is designed, by which mobile users can get the interested video content from other mobile devices. The algorithm is applied in a gymnasium scenario, for a point to point multi-hop video sharing application in ad hoc network that is self-organized by the mobile terminals. A prototype is implemented for this...
An application scenario embracing the area of Intelligent Transportation Systems (ITS) is studied in this paper. The infrastructure of the application scenario is wireless sensor networks with mobile sinks. The WSN is query-based and with multi-hop transmission for data sensing. The application-specific network architecture was introduced and exploited. The detailed routing algorithm as well as its...
The paper analyzes the impact of wind generation on the regulation and load following requirements of the California Independent System Operator (CAISO). These requirements are simulated and compared for the cases with and without wind generation impacts included into the study for the years 2006 and 2010. Regulation and load following models were built based on hour ahead and five minutes ahead load...
