Reliability And Economy Research On Electricity Market Operation

Critical accidents, such as the America-Canada blackout happened in August 14, 2003, have taken place constantly, which makes countries all round the world realize more profoundly that with further innovation in electric power industry, the conflict between electricity market operation's reliability and its economy will become more and more phenomenal. It has become a great challenge for electric power department that how to supply the customers at a necessary reliable level and follow the principle of fairness, honesty and openness in the meantime at a cost as low as possible, which makes research on electricity market operation's reliability and its economy become a focus. Value-engineering theory is one of the new technologies in industry management domain after the World War â…¡, its main idea is to offer the customers the service needed at the lowest cost. In a word, value-engineering can be applied to where resources are exploited. Considering optimizing resources deployment is one of the main objects in electric power industry's innovation, this essay puts electric power commodity a new value-engineering connotation after analyzing its three elements that is, function and cost and value. On this base, this essay applies value-engineering theory to research the economy and reliability of electricity market operation to meet the power demands of customers, to improve the dealing flexibility of electric power commodity, to make electricity market develop continuously and steadily and reasonably so as to get maximal social economic benefits.Electric price is the fulcrum controlling power trade and plays a role in price guidance of electricity market. Aimed at reliability price and compensation problem of distribution price system in this essay, the value-engineering and electric power system reliability techniques are applied to presents a reliability price and compensation mechanism and to change the illogicality of consume electric power profit transfers among customers so that the market equality can be embodied. According to the influence of electric commodity function on its price and distribution system reliability technology, this essay presents foremost a double parameters synthetically pricing method based on the user's reliability indices demand, which effectively offsets the deficiency of single parameter pricing method. At the same time, recognizing effectively the reliability compensation function accords with customer's willing, the reliability electric price and compensation mechanism that are accommodated to electricity market operation be formed. Applied to RBTS-BUS6, the new mechanism is proved to be able to give attention to both the supplier and the customer's benefits, realize the idea of excellent price for good quality and compensation for blackout, improve continuously operation efficiency of distribution market. Generating power market is the primary filed, which is open in electricity market and also relatively matures part. Analyzing the traditional generating power market operation mode synthetically, this essay presents the novel competitive generating mode based on double influence the function and price of an electric commodity on generation plants and customers. The mode regards the electric power plant as independent competitive unit and presents the value-evaluation-factor of the electric power plant, based on which the combined optimality model of competitive generating, considering economy and reliability is established. The model takes the minimal sum of the plant-value-evaluation-factor of all competitive power plants and the minimal total cost of the customer's power consuming as double objects optimization function, and takes the power balance of between systems, the limits of power contribution of every power plant, and so on, as the constraints of the model. Besides, the original values of different competitive power plant's power contribution is determined by the equal loss of micro-incremental-rate principle and the model is solved with the techniq...
