President Obama called for doubling the share of renewable energy in the nation's supply in three years. California has a renewable energy target of 33% percent by 2030. These bold commitments need transformational strategies to achieve them. Government policies to achieve the ultimate goal of carbon reduction in electric energy systems are to (i) increase renewable penetration, and to (ii) introduce...
Defining and evaluating operational equilibriums in real-time market, constrained by operation risks and economical biddings, is in the center of market operation and its enhancement. For example, in the two-settlement market design, reliability unit commitment is an important stage to bridge day-ahead market with Real-time system operation, which commits additional units to cover forecasted load...
The ISO market design has evolved over time using traditions development, economic theory, power system operations heuristics and operational experience. Early market design made simplifying assumptions and approximations often due to the inability to solve the more detailed design. Complicating features in market design such as reactive power, unit commitment, switching of transmission assets, renewable...
Due to the energy challenges in the world, new types of generation technologies, such as renewable energy based generators, attract great attention and are being quickly developed, which results in the dramatic developments and changes in modern power systems, the communication technologies play a increasingly important role in guaranteeing the power system's stability, reliability, and security....
Currently, the New England power system is highly dependent on fossil fueled generating units. The region has a significant potential for developing renewable sources of energy, including substantial inland and offshore wind resources within the region as well as in neighboring areas. ISO New England (ISO-NE) has identified the potential for up to 12,000 megawatts of wind resources within New England...
Demand response (DR), coupled with smart-grid technologies, will be a big initiative for energy companies in the US for the next 3-5 years. This paper summarizes the key technical and IT challenges that will need to be solved to properly deploy DR at the wholesale and retail levels.
With the recent emphasis on environmental issues and concerns for global warming, many states have adopted aggressive Renewable Portfolio Standards (RPS) requiring electricity suppliers to obtain a minimum percentage of their power from renewable energy resources by a given date. Among various states, California leads with an RPS of 20% by 2010, and 33% by 2020. Most renewable resources, by their...
A key requirement of electric system operation is the ability of system operators to manage all types of variability and uncertainty. Integrating large-scale wind power into electric system operation increases variability and uncertainty that can impact supply and demand balance performance requirements. Many Independent System Operators (ISOs) are in the process of addressing these challenges. The...
Today, a large number of wind generator interconnection requests have been queued and are being processed. The generator interconnection group study is a way to reduce the generator interconnection cycle time and increase interconnection certainty. However, it is very challenging to identify the “best” transmission upgrades for a large group of generator interconnections. It is also very important...
This panel session will highlight the market impacts of integrating large-scale variable generation into wholesale electricity markets. The focus will be on examining the impacts of variable generation on market price volatility and the resulting impact on market behavior. Variable generation affects day-ahead and real-time energy markets, as well as markets for ancillary services. Market price volatility...
This paper describes the process required to adapt a conventional EMS Simulator for testing the Real-Time Electricity Market. The paper discusses the need and requirements for the simulator. CAISO's traditional EMS Dispatcher Training Simulator was modified and coupled with CAISO's Market Applications to act as a real time Market and Grid Operation Simulator. This new simulator provides realistic...
Capacity markets have been launched at several ISOs in the US. Many questions arise: Is a capacity market for missing money or reliability? What is a capacity product? How to price the capacity product? These questions are nontrivial and have been discussed in the literature mostly from the economics perspective. This paper attempts to address them from both economics and engineering perspectives...
This paper presents updated results from a Monte Carlo simulation method of operational needs created by variable generation renewables coupled with a Production Simulation methodology to assess whether the California ISO's existing generation fleet can provide the needed flexibility for ramping, load following and Regulation under a 20% Renewable Portfolio Standard. The production simulation methodology...
This paper describes the implementation of demand response (DR) program in CAISO. A Participating Load Pilot (PLP) program has been implemented in CAISO system during summer 2009. This is the first time that a cross-section of residential, commercial and industrial customers has been in the PL (Participating Load) program and modeled in CAISO systems. This paper takes this Participating Load Pilot...
Over the past few years, the Midwest ISO has experienced a surge in requests to interconnect large amounts of wind generation, driven largely by a favorable political environment and an abundant wind resource in the Midwestern US. This tremendous influx of proposed generators along with a highly constrained transmission system adversely impacted interconnection queue processing, resulting in an unmanageable...
This paper outlines the reasons why COES wants to adopt the CIM standard and the road map to make its information systems compatible with CIM. COES information system is an internally developed system (SICOES), and would be the starting point to adopt CIM. It is necessary to integrate the data of the third party software used in COES for power system analysis activities to the SICOES central equipment...
This paper discusses launch of the energy market in 2005 and the ancillary services market in 2009. Despite the growth in demand resource participation in the Midwest ISO markets since the launch of the Ancillary Services Market (ASM) and Resource-Adequacy requirements, more can be done to enhance opportunities for demand response and the positive impacts it creates for all involved in the wholesale...
Our research team is developing an agent-based test bed for the integrated study of retail and wholesale power markets operating over transmission and distribution networks with smart-grid functionality. This test bed seams together two existing test beds, the AMES Wholesale Power Market Test Bed and the GridLAB-D distribution platform. As a first step, we have designed an integrated retail/wholesale...
This paper provides an overview of on-going transmission development to meet environmental policies in the State of California. Currently, load serving entities in the State of California are required to procure 20 percent of its energy with renewable generation by 2010 and the Governor's Executive Order sets a target of 33 percent Renewable Portfolio Standard by 2020. To meet this target by 2020,...
