A Study On The Affection Of Price Mechanism To Capacity Adequacy

Power System Operation is closely related to people's production and life, electric power has not enough capacity that will pose a threat to society industry, thus ensuring ample generating capacity is essential to the operation of the power system.In order to maintain a reliable electricity supply ,during the power industry reform, ensuring sufficient generating capacity is one of the core problems that need to be solved. Solving the problem of generating capacity has plenty of means, including administrative measures and market-based instruments, but until now the same conclusion has not been recognized about how to guide the investment .In the current market, the price of a single formulation mechanism,two-part price mechanisms and the development of ICAP mechanisms is commonly used, they are mainly to solve the problem about the system capacity sufficient ,However, these price mechanisms have not yet reached any consensus about solving the problem of system capacity . the price of a single formulation mechanism can be achieve social ideal installation, but the loss of load time is longer and the value of lost load is too large; two price mechanisms can solve the issue that the loss of load time is longer, but can not achieve the social ideal installation , Based on the analysis of two kinds of the price mechanism,this paper studys two-part electricity price mechanism that combines price cap .The electricity price mechanism solves the the social ideal installation of the problem and analyses pricing mechanisms'influence on system capacity sufficient ,specifically include the following three points:1.Load demand changes, the simulation analyzes two kinds of price mechanism's response process with the load changes , through comparatively analyzing the simulation's results ,testing the advantages and disadvantages of a single system of pricing mechanisms and two-part pricing mechanism.2.Simulation analyzes the change process of installed capacity when two kinds of price mechanism reach steady-state point .3.In a particular value, combining with two price mechanism of the price-cap system, simulation analyze the load change when achieving the community's best installation .In this paper, simulation analysis that combines with price cap system of the price mechanism achieves social ideals installation and can reduce the loss of load time at the same time, and can solve the disadvantages of a single system of pricing mechanisms and two-part pricing mechanism has certain research value.
