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.

针对"厂网分开，竞价上网"的电力市场运营模式，本文主要完成了以下研究工作：1研究了发电商不同的竞价上网策略，利用供给函数均衡方法，建立了发电商的竞价上网策略模型，给出了市场均衡解的具体解法；讨论了不同条件下发电商的竞价策略对市场的影响，并获得了发电商的最优上网竞价策略，明确了竞价上网与峰谷分时电价之间的影响因素；利用电力系统负荷曲线，建立了发电商最优竞价策略与峰谷分时电价之间的相互联系，通过仿真算例分析了峰谷分时电价与发电商最优报价之间的相互影响。2提出了"厂网分开，竞价上网"电力市场模式下，考虑发电侧竞价和用户侧博弈等风险因素影响，峰谷分时电价理论建模在规避电网企业运营风险，保护供电方与用户双方的利益、确定用户响应曲线、划分峰谷时段、设置合理的电价拉开比等方面所应遵循的基本原则，在此基础上建立了适合电力市场模式的峰谷分时电价模型。3从原理上分析了需求侧实行峰谷分时电价策略，对削峰填谷，提高负荷率，改善负荷曲线形状，降低电力系统的电能损耗和电压损耗等方面的影响，并进行了仿真验证。

It thinks that the promotion of ESO system is the requirement to deepen the current state-owned enterprise reform and the construction of modern enterprise system. It is urgently needed by the hi-tech enterprises to attract talents and avoid brain drain. The long-term stimulation mechanism such as stock option has better effect in comparison with the traditional salary mechanism such as basic wage and annual bonus. Meanwhile, with the expansion of use scale of the long-term stimulation mechanism such as stock option and greater elasticity of the performance of the whole salary, the stimulation effect of the whole salary will be strengthened.

认为ESO制度的推行是当前深化国有企业改革，建立现代企业制度的要求，是高科技企业吸引人才、避免人才流失的迫切需要；其与基本工资和年度奖金等传统薪酬机制相比，股票期权等长期激励机制的激励效果更好；同时随着股票期权等长期激励机制使用规模的扩大，整体薪酬的业绩弹性增大，使整体薪酬的激励效果增强。
