This paper studies the problem of congestion management model that based on quoted price adjustment in the real-time electricity markets, dealing with two cases : opening the generator side only and opening the generator side and load side simultaneously, introduces the congestion factor and establishes a novel optimal congestion cost model for each case. Furthermore based on the max-mini theory,...
Although the financial crisis shrinks oil price, human as an entire race still face the future of a hot, flat and crowded world [1]. Therefore, a critical transformation from our traditional energy consumption manner of fossil fuel combustion must be made. After years of endeavor in research and experiment, a number of Renewable Energy Sources (RES) has already become technically available as alternatives...
With the impact of interruptible load (IL) to power system and the security of power grid, this paper points out that IL is one of the security providers. Then the model of power grid operation security cost is presented. The security cost consists of the generating reserve cost, the IL cost, the rescheduling cost and the expected system instability cost. A lingo program is used to optimize the model...
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...
