Research On Theory And Application Methods Of Electricity Surveillance

As electricity industry reform deepens, it's needed to establish efficient regulation system, reduce reform costs and risk, and promote efficiency of electricity industry. In this thesis, mechanism design theory and its application in electricity surveillance are studied. The theory and methods in the main sectors of electricity regulation are also studied.The mechanism design theory based on incentive compatibility and its applications in electricity surveillance are studied first in this thesis. The fundament of incentive compatibility is brought forward. New design criteria are established, which make incentive compatibility more practical. Furthermore, following the criteria to design mechanism, the global optimization of the benefits of participants and public can be achieved and the process that participants choose their optimal strategies can be simplified. The new criteria settle the foundation stone for the full application of incentive compatibility in electricity surveillance. Then, by applying the new criteria, the vertical monopoly mode of electricity industry and the System Margianl Price (SMP) pricing method in power pool are assessed to discover the process how mechanisms affect the market efficiency and participants'strategies. New competition mode is realized in generation market.This thesis establishes an index system for generations'market power analysis, as well as a novel method which can precisely, subjectively and fully assesses market power. In the method, transmission constraints, market concentration and demand-supply ratio are integrated. Thus, it can quantitatively analyze the impacts of net constraints on the market power, and identify the critical reasons that result in market power and its degree. The new method can offer evidences to mitigate market power.This thesis presents an assessment method based on workable competition to evaluate whether a generator execises its market power. It's no impossible that electricity market is perfect competition. So, it's irrationality to assess market powerabuse based on perfect competition. This thesis brought forward to assess market power abuse based on workable competition. By comparing the market operation status with four status benchmarks of workable competition, Four methods are brought forward, which are named as period of time benchmark method, power plant benchmark method, node benchmark method and HHI benchmark method. They have high maneuverability. They can be used to assess market power abuse truly.The regulation of transmission and distribution enterprises is studied in this paper. The behaviors of enterprises to aggrandize costs of service are summed up. The plan ex post facto assessment methods are proposed to prevent irrational plan. Build-Operate-Transfer (BOT) mode is recommended in power grid investment. The BOT can introduce competition in power grid construction and keep monopoly in power grid operation. To ensure power grid open access without discrimination, the meaning of open access is classified to consumers, to plants and between inter-grid. The methods to monitor open access are brought forward. Dispatching and trading regulation methods are also studied in this thesis. Three methods are advanced, which called based output gap method, based price gap method and constraints analysis.This paper establishes a quite complete system of electricity surveillance fundamental theories and studies the surveillance methods in the main sectors, which are of great value to building up a scientific and efficient electricity regulation system in our country.
