A method of optimizing downlink communications between a base station and mobile stations in a wireless communication system involves: identifying users that have a modulation control scheme (MCS) power value greater than a reference power value as high power users; for each of the high power users, calculating a power difference being a difference between a geometry value associated with each of the high power users and a reference geometry value associated with the reference power value respectively; summing the power differences in a power pool; identifying users that have an MCS power value below the reference power value as low power users; associating increased geometry values with at least some of the low power users while depleting the power pool by corresponding amounts until the power pool is depleted; and determining new MCSs for at least some of the low power users based on the increased geometry values.

A power pool overload centralized decision-making real-time emergency control method, includes: the host computer reads in the operational real-time data of the electric network from the energy management system and the control device through the communication interface; the host computer computes the optimized emergency control project based on the algorithm of the elimination line of the optional control measurement of the generator and the load and the loading combination performance index of the transformer; the host computer sends down the control project to the control device through the communication interface, and realize the control project through the function of the control device. The invention makes full use of the energy management system and the control device, from the overall situation of the electric network, solves the centralized decision-making and the real-time emergency control of the overloading of the power pool, which has correct and reliable judgement to the overload, fast action and the chain failure of the single node action in the traditional technology is not present.

The invention provides a combined regenerative energy power supply device which comprises a wind power generation unit, a photovoltaic power generation unit, a high-capacity energy storage element and a coordination control unit, wherein the high-capacity energy storage element is used for storing electric energy; the coordination control unit is used for enabling the wind power generation unit or the photovoltaic power generation unit to charge the high-capacity energy storage element when the electric quantity produced by the wind power generation unit and the photovoltaic power generation unit is higher than the demand of users in a region, and supplying power to an outside power pool system under the condition that the electric energy is surplus after the charging of the high-capacity energy storage element is finished; and the coordination control unit is also used for cutting off the wind power generation unit and the photovoltaic power generation unit and enabling the outside power pool system to charge the high-capacity energy storage element and supply power to loads of the users in the region when the electric quantity produced by the wind power generation unit and the photovoltaic power generation unit is lower than the demand of the users in the region. According to the invention, line loss and construction investment caused by remote locations of power generation places and long distances from loads can be effectively reduced.
