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...
In this paper, first, two new criteria, which are titled social welfare percent (SWP) and congestion cost percent (CCP), are defined for static transmission expansion planning in restructured power systems. Then by a simple example it will be shown that none of the already presented market-based criteria could completely and truly evaluate the transmission network expansion from market view. Hence...
Before deregulation, th Korea Electric Power Corporation (KEPCO) had been a vertically integrated monopoly over power generation, transmission, and distribution. However, the generation competition market based on Cost based pool (CBP) began in April, 2001. The KEPCO generation department has been allocated into six independent GenCos. Before the reform of the power industry that took place in South...
Renewable energy sources are becoming more and more important for power systems. With increasing sizes and a mandate to operate as financial entities seeking to maximize benefits in an electricity market, power systems require highly effective planning tools. In this paper, an optimal capacitor planning method based on optimal power flow is proposed for a power system with wind generators and PV arrays...
As electricity market participants are prevented from investing in transmission facilities and services in most markets, so transmission expansion may have not sufficient stimulation for competition within the market participators. Therefore an important issue in transmission expansion planning (TEP) is to facilitate competition among GENCOs. In order to make transmission expansion more competitive,...
The need to attract private capital was one of the main drivers for the deregulation of electricity markets in Brazil. The early 90s scarcity of public resources for infrastructure investments was responsible for the need of private funds. However, the deregulation process was not as straightforward as firstly conceived, and adjustments had to be made. This paper analyses the causes and consequences...
With a significant number of states in the U.S. trading electricity in restructured markets, a significant proportion of capacity expansion in the future will have to take place in market based environments. However, since a majority of the literature on capacity expansion is focused on regulated market structures, there is a critical need for comprehensive multiperiod, multi-player, capacity expansion...
This paper presents a multi-year transmission expansion planning (TEP) model which considers the transmission congestion and the impact of generation investment cost in the planning horizon. The Benders decomposition approach is utilized which decomposes TEP into a master problem and two subproblems representing security and optimal operation. The operation cost due to congestion (OCC) is considered...
