High penetration of wind power has posed great challenges to power system operators. Extensive research has been done aiming to improve the power system operations. Various mechanisms such as stochastic unit commitment and reserve calculation methods have been proposed. However, the power system operators may have different views on the research results due to practical constraints. This paper looks...
State and potential federal policies are expected to increase renewable generation in North America in the immediate future. Much of this growth will be from variable resources such as wind generation and solar photovoltaic (PV). As the amount of variable generation increases, the reliability of the bulk power system can be negatively impacted if provisions are not made to accommodate the additional...
State and potential federal policies are expected to significantly increase renewable generation in North America in the immediate future. Much of this growth will be from variable resources such as wind generation and solar photovoltaic (PV). As the amount of variable generation (VG) increases, the reliability of the bulk power system can be negatively impacted if provisions are not made to accommodate...
This paper reviews the design and operation of a number of large, regional organized markets in the US, as well as the operation of stand-alone single balancing area bilateral markets, from the viewpoint of integrating large amounts of variable output renewable energy sources. Significant differences between the two types of markets are noted. In addition, a series of shortcomings of the first generation...
Ireland has some of the most favourable wind conditions in the whole of Europe. Wind production, in the mainland as well as offshore, is expected to grow rapidly during the coming years, as evidenced by the fact that some 6000 MW of wind generation is currently awaiting connection to the grid onshore. Given the massive potential for the exploitation of renewable energy resources off the coast of Ireland,...
Wind generation has been recognized as one of the most important components in Renewable Portfolio Standard (RPS). It becomes a critical task for the power engineers to find solutions in integrating wind generation reliably and economically with the power grid. The intermittency of wind generation and the potential need for adequate transmission expansion are the major concerns in wind technology...
The presentation will show a history of past deployments over the past 4 years. For selected events, we will discuss curtailment duration and the reason that triggered these deployments. A specific event that we will discuss occurred in February 2008 when ERCOT experienced a dramatic increase in load combined with a large drop in wind generation, which led to a system-wide deployment of Load Resources...
New Wind generating facilities are the fastest renewable resource to install and interconnect to the power grid. Wind generation, however, presents the largest operational challenges. Wind generation energy production is extremely variable; it often produces its highest energy output when the demand for power is at a low point. During some periods of the year, wind generation is difficult to forecast...
Increased connections of wind power in the Great Britain (GB) transmission system had triggered the need to review the fundamental principles behind the deterministic Great Britain Supply Quality and Security Standards (SQSS) that has been used for more than 5 decades. This review analyses the necessary upgrades to improve the efficiency of transmission system operation and capacity required to accommodate...
