This paper describes use of advanced battery energy storage systems to support integration of wind generation with power systems. Two wind integration projects using A123 Systems' proprietary Nanophosphate® lithium iron phosphate battery technology are described to provide examples of energy storage applied for wind integration. The first example is the Tehachapi Wind Energy Storage Project by Southern...
Ancillary services markets have been developed in many of the restructured power system regions throughout the world. Ancillary services include the services that support the provision of energy to support power system reliability. The ancillary services markets are tied tightly to the design of the energy market and to the physics of the system and therefore careful consideration of power system...
This paper investigates the potential of providing a variety of energy storage services by directly control the thermostatically controlled appliances (TCAs) from a centralized controller. Dispatch algorithms for the controller to arrange the turn-on and turn-off time and duration of individual TCAs are presented. The control goal is to operate each TCA within the customer-desired temperature range...
This paper presents two extensions to the literature on modeling of wind and solar integration in the California ISO footprint, as well as results from a large-scale regional simulation [2]. First, the paper presents a two-step methodology for simulation of power systems with high penetration of variable generation resources, such as wind and solar. The first step is a statistical model that calculates...
Large amounts of wind and/or solar energy will have an impact on bulk electricity markets. This panel presentation will provide insight to how scheduling and dispatch rules can help to efficiently integrate wind and solar generation. Possible proxies for wind and solar capacity values that may be useful in capacity markets are also discussed.
Three critical cascading faults with nearly 2000 WTGs (Wind Turbine Generator) tripped took place in China on early 2011, from which the reactive power and voltage control issues for large wind farms are spotlighted. Some key factors inducing the cascading trip are surveyed by this paper firstly, including WTGs voltage distribution, dynamic reactive power reserves and coordination of tight-coupled...
Wind generation is playing an increasingly significant role in many electricity industries around the world. It has very different operational characteristics from existing generation and the integration challenge is to facilitate wind in achieving its maximum energy, environmental and wider societal value. Maximizing energy value is a particular challenge for electricity arrangements as penetrations...
The development of large amounts of wind and/or solar energy will have an impact on bulk electricity markets. These variable generation sources increase the level of variability and uncertainty that the power system operator must manage. In this paper we discuss the impact that electricity markets have on the wind producer, using examples from the Nordic system. We also describe two market structures...
This paper summarizes the California ISO's renewable integration studies performed to evaluate the need for flexible resources in the year 2020 as the fleet of resources transitions from flexible conventional resources to intermittent and variable resources under higher renewable penetration levels. California's Renewable Portfolio Standard (RPS) requires that 33% of all energy consumed be met by...

This paper describes basic technical aspects to consider when applying wind generation to transmission grids that include series-compensated transmission lines, and some thoughts on how the industry can manage this combination in the future.
