Competition and Cooperation in Deregulated Bulk Power Markets

Current US electricity markets are showing improvement, reflecting improvement in the economy as a whole. However, we do have several concerns for the future. The risks which accompany new power plant construction have led the industry, as well as others, to seek out new alternatives. Canadian imports, cogeneration, and improved bulk power markets all have a role to play in future utility planning. But, I believe we must still retain the option of new central station generation. Current attempts in the US to remove capital formation incentives through tax reform, to prohibit construction work in progress in the rate base, and to exclude surplus capacity from cost recovery are examples of public policy decisions which we believe would be counterproductive to providing low cost, reliable power to consumers. Rather, we believe public policy should focus on providing the utility industry with the opportunities to make the best long-term economic decisions on behalf of its customers.

Bulk Power

Transmission planning should seek to maintain or improve system security over time and facilitate robust wholesale power markets by improving transmission capacity for bulk power transfers across wide regions It includes finding the optimal plan for the electrical system expansion, it must specify the transmission lines and/or transformers that should be constructed so that the system to operate in an adequate way and in a specified planning horizon. In this paper a methodology is proposed for choosing the best transmission expansion plan using Transmission security based on contingency analysis. A procedure using sensitivity analysis is used to evaluate potential transmission connections and that provide the most improvements to overall system security .The methodology is applied to a six bus Garver system The result obtained with the proposed method are validated with the results reported in the earlier research papers.

Bulk Power

In most U.S. market sponsored demand response (DR) programs, revenue earned from energy markets has been relatively low compared to DR used for capacity markets and ancillary services. This paper presents an aggregated DR model participating in the bulk-power market as a service through a pool-based entity called demand response exchange (DRX). Using the DRX structure, DR providers can participate in energy markets as a service to benefit bulk-power market entities. The benefits and challenges to each market entity using DR-as-a-service are presented in an extended review. The DRX model in this study is a market entity that operates with the day-ahead market to select DR offers that minimize electric utility payments. A case study was performed using the proposed DRX model on the IEEE 24-bus system, augmented to represent actual bulk-power market prices to study factors that influence utility payments under the DRX-market paradigm. Two high-price days of the PJM market were simulated, and it was shown for a single day on the augmented test case that spending $69,955 for DR-as-a-service results in a reduction of utility payments of $864,199. The day-ahead generator supply curve, network congestion, and DR curtailment were found to be the most influencing factors that impact the benefit of using DR-as-a-service.
