The main research results in this dissertation can be given as following:Firstly, the bidding strategies and affections of generation companies on the TOU power price are analyzed; Supply function model is employed to simulate the bidding strategies of generation companies in power pool. Some meaningful results are obtained through the proposed equilibrium equations model, when different bidding parameters are selected to maximize profit of suppliers, such as the the numeral of generation company, the block bidding, and power demand elasticity. Based on these results, the affections between the bidding strategies and the TOU power price are discussed.Secondly, the important principles consider the factor of bidding strategies of generation companies and consumers gaming strategies are proposed to constitute the new TOU power price model under present electricity market. Based on these pricinples a new mathematical model of TOU power price is constructed, to evade electricity market risk, partition the peak-valley, ascertain the consumers' response curve, and protect the ambilateral profits.Thirdly, the affections of the TOU power price strategies for reducing the network loss, adjusting node voltage, improving load curve of power system, and protecting the consumers' benefits in electricity market are analyzed with applications of a city real time load data of Jiangsu province.

The basic principle and hierarchical frame of FSR decision-making solving for DN is proposed creatively based on reliable knowledge. The categoricalness and high efficiency of decision-making solution set for FSR are ensured. The principle layer controls and realizes the search range and realization mode. The hierarchy and subarea search is performed, whose optimal rule is considered at the same time in order to ensure the solving rapidity. The decision-making realization layer forms the operation sequence of switch based on the trunk network set algorithm. The categoricalness and high efficiency of decision-making solution set for FSR is ensured.
