This paper presents a market-based transmission expansion planning model and compares it with a traditional reliability-based transmission planning model. Reliability-based transmission planning tries to install new lines at minimal cost while fulfilling system reliability criteria. Market-based transmission planning, on the other hand, seeks investment opportunities so that network expansions can...
This paper reviews the high performance technical computing (HPTC) applications in Midwest Independent Transmission System Operator INC (Midwest ISO or MISO) various operation functions. The paper briefly describes the day ahead market, real time market and FTR market. Its ancillary service market design is presented as an example of the application of the high performance technical computing. The...
In economic valuation - cost-benefit analysis - of transmission upgrades under competitive market environment, cost of transmission facilities is determined based on the annual carrying charge and benefit is defined based on the concept of `social welfare maximization'. A transmission upgrade is chosen to be built when its benefit exceeds its cost plus some percentage adder to account for future uncertainty...
Electric power systems are extremely complex. Therefore, system operators and planners are faced with difficult problems, which are uncertainty of power system. Also, they have to obtain best efficiency with least cost of investment. Transmission network expansion planning (TNEP) vases on reliability, and considers economic aspect. This paper presents well-being method and cost-optimization method...
Midwest ISO's real-time market design with energy and ancillary service co-optimization is reported in this paper. The key components of Midwest ISO's real-time market are described including intra-day reliability commitment, transmission security management, real-time dispatch and pricing. The RT SCED formulation at the core of the real-time dispatch and pricing market is presented. Numerical examples...
This paper describes the multi-step value based transmission planning process for joint coordinated system plan with the consideration of large scale wind generation over the Eastern Interconnect footprint. As the result of the coordination of multiple RTOs, the conceptual transmission expansion plans are developed to meet both reliability and economic needs. A combined EHV AC and HVDC transmission...
The Midwest ISO is the RTO for 15 states in the central U.S. Multiple, interlinked planning processes are in progress annually within the Midwest ISO. The Transmission Expansion Plan is a 10 year plan that recommends the projects approved for construction. The Generation Interconnection and Transmission Service planning is an input to the Transmission Expansion Plan. Mid range Targeted Studies are...
To incorporate large-scale wind generation in the Midwest ISO footprint, bulk transmission planning is necessary. In this paper, transmission planning for large-scale wind power is explained in detail. In expansion planning, the wind generation capacities are estimated from state Renewable Portfolio Standards (RPS) and the wind generator locations are chosen based on best wind source zones. From economic...
As the electrical power industry is restructured, the electrical power exchange is becoming extended. One of the key information used to determine how much power can be transferred through the network is known as available transfer capability (ATC). To calculate ATC, traditional deterministic approach is based on the severest case, but the approach has the complexity of procedure. Therefore, novel...
In this paper, we describe an economic model of market-based transmission planning, employed at PJM Interconnection, the largest regional transmission organization (RTO) in the U.S. We call this model the ldquoMarket Efficiency Analysisrdquo model. The salient feature of this model is that it is based on the forecasted congestion in the PJM system for future years, based on the best possible system...
This paper investigates the 115 kV transmission system development plan of Electricite du Laos (EDL), specifically for the transmission line projects in the Central-1 and Northern regions of the Lao PDR for the years 2010-2020. The steady-state power flow analysis at peak demand conditions is based on N-l contingency criterion. The adjustment in transmission system development plan of EDL is to improve...
The SuperOPF provides a framework linking the short-run criterion of "operating reliability" and the long-run criterion of "system adequacy" on an AC network. This is accomplished by allowing for load shedding as an expensive option to meet contingencies. The high cost of "energy-not-served" implies that some equipment can be very valuable in contingencies if it reduces...
In a competitive electricity market, the transmission costs should be fairly distributed amongst the users of the transmission facilities, in order to attain optimal usage of the transmission facilities and to provide correct economic signal for future generation planning and load placement. In this paper, transmission costs are divided into three components; i.e. actual transmission usage cost, unused...
This paper investigates the transmission system development plan of Electricite du Laos (EDL), specifically for the transmission development projects in the Central-1 and Northern regions of Lao PDR for the years 2010-2020. The power flow analysis at peak demand conditions is based on N-1 contingency criterion. The adjustment in transmission system development plan of EDL is to improve the reliability...
This paper discussed the basic concepts, criteria, procedures and methods in probabilistic transmission planning. The main purpose is to capture probabilistic characteristics in power system planning including uncertainties in load forecast, generator locations, and random failures of system equipment. Two key steps in probabilistic transmission planning are probabilistic reliability evaluation and...
The ISO New England planning process calls for providing reliability, economic, and environmental information to participants. This includes summaries of loss of load expectation studies, transmission adequacy evaluations, environmental issues and performance, and locational marginal pricing, production cost, and congestion information. Short term certainty of resources is provided by the forward...
