Abstract. By utilizing interruptible load management can be quickly and flexibly to eliminate the root causes of congestion on the line, based on lowbidding interruptible load have priority in electricity markets. This paper selects the interrupt interruptible load at the same time taking into account the sensitivity and interruptible load costs factor. By building mathematical models of congestion sensitivity, and combined with interruptible load costs form the new impact factors, as the basis of choice of interruptible load adjustments needed. A congestion management model was proposed with the goal of minimizing the congestion elimination cost, and has attempted to find the solution to it. Finally, a practical case is designed to validate the economic and validity of the method. And have achieved the expected effect.

In order to provide reserve power supply, consumption dispatch can be integrated into the conventional generation dispatch model. This serves as a feasible approach in connecting intermittent power sources such as hydropower into the power grid. An integrated generation-consumption dispatch model with hydropower is presented considering the consumption dispatch mode, such as consumption stimulation, interruptible load management, and price response, etc. Practical case studies show that price-responsive loads and interruptible loads tend to exert great influence on the load distribution which lead to a reallocation of generation among thermal generation units, run-of-river and storage hydropower generation units, which favours the total reservoir storage of the system so that the overall system operational economy can be improved.

The Cost

In this paper interruptible load management model via incentive compatibility is researched. Simulated the interruptible load capacity and disruption of economic compensation of the interruptible load management with using MATLAB and compare the cost of interruptible load management and construction of standby units, find that interruptible load management can reduce the cost of electricity companies. But it should be noted that when the interrupt the load is too large, the implementation of interruptible load management will increase the operating costs of the utilities.

This paper presents a novel technique to analyze, manage and price transmission congestion in electricity markets based on a simple auction mechanism. The proposed technique is basically an iterative rescheduling algorithm, relying on an ``on-line'' evaluation of the transmission system congestion, as defined by a System Security Index (SSI), and associated sensitivities, which are all computed based on formulas that account for voltage stability constraints as well as thermal and bus voltage limits. The methodology is tested using a 3-area test system, a 6-bus test system with both demand-side bidding and inelastic demand, as well as a 129-bus model of the Italian High Voltage transmission system with demand-side bidding. The results obtained for these test systems with the proposed technique are compared with similar results obtained from an optimization-based method.

The power transmission network has the problem of management due to congestion in the open access system. Power flow due to transactions in transmission lines can cause overloads. This condition is known as congestion. There are several alternative methods for congestion management which are suitable for different electricity markets. In this paper the Locational Marginal Pricing (LMP) method is discussed for an assessment of transmission congestion management and results are obtained to manage the transmission congestion such as redispatching existing generators outside the congested area to supply power to the customer. The primal dual IP algorithm is used to calculate the LMP’s and congestion cost values. The proposed work has been implemented on a 14-bus test system to illustrate the advantages and disadvantages of this method
