Research On Power Demand Side Management Mode

Along with the economic development of China, the bottleneck question of energy will be more outstanding, especially since the past 10 years, the growth rate of load is greater than that of the quantity of electricity, which makes the load rate of electric network drop down, peak valley disparity increase. This will bring difficultly for peak transfer and economical operation of electric network. To slove this problem, increasing only the investment of electric power plant will cause extreme waste of energy, so it is important to carry out energy-conservation on the demand side.Power demand side management (DSM) is internationally fashionable resource management technology, through adopting reasonable hortative instrument, it can lead the power consumers to change their power consuming mode so as to be beneficial to flat the load curve. In this paper, demand side management mode is analyzed in detail, which provides important reference to DSM.Firstly, based on comprehensive investigating on the advanced experience in other province or overseas, this paper presents the potential of implementing DSM. Interruptible load management (ILM) is an important field of DSM, on the basis of the principle of ILM, combining with the actual environment, this paper introduces the interruptive load contract and its mode, and firstly leads the interruptive load into dispatching field, which offers new idea to power transmission congestion management in the electricity market. Time-of-use (TOU) power price is one of the effective measures in DSM, with the analysis of its principle, a new TOU power price model which adapts to the innovation of power market is developed, which provides the basis to build the power price. Combining with actual situation of Hunan power network, this paper analyse the steps carrying out ILM and TOU power price in Hunan province, five technologies such as green light also have been selected to give technical and economic analysis, which can effective coach the DSM programminig of power system in Hunan province.
