Low-carbon power investment decision-making method in power capacity market under the condition of new energy access

Abstract

The invention discloses a low-carbon power supply investment decision-making method of a power capacity market under a new energy access condition. The low-carbon power supply investment decision-making method comprises the following steps of 1) building a mathematical model of the capacity market by taking low-carbon power supply installed capacity subsidy as an incentive method of the capacity market; 2) building a mathematical model of an electric energy market; 3) building a mathematical model of simulating a balance market; 4) building a comprehensive profit model of a power generation set according to the mathematical model of the capacity market, the mathematical model of the electric energy market and the mathematical model of the balance market; and 5) calculating annual comprehensive profit of the power generation set according to the comprehensive profit model of the power generation set, building a low-carbon power supply investment model of the power generation set according to the annual comprehensive profit of the power generation set, and estimating an investment state of the power generation set according to the low-carbon power supply investment model of the power generation set. By the method, the simulation of the capacity market is introduced to make a decision of low-carbon power supply investment of the power capacity market.

Description

technical field [0001] The invention relates to a low-carbon power supply investment decision-making method, in particular to a low-carbon power supply investment decision-making method in a power capacity market under the condition of new energy access. Background technique [0002] Power investment decision comes from a mature and complete branch of power system: power optimization planning. However, with the deregulation of the power system and the deepening of market-oriented reforms, it is no longer possible to determine the construction of generating units based on administrative planning alone, but to stimulate power investment decisions based on the profitability of power generators participating in the power market. [0003] Initially, the profits of power generators only come from the electric energy market and the balancing service market in the electricity market. However, in the 1980s, due to insufficient profits in the above-mentioned markets, American power g...

Problems solved by technology

However, in the 1980s, due to insufficient profits in the above-mentioned markets, American power generators closed down one after another, which made the power system insufficient reserve capacity during the peak period of power consumption, which led to large-scale power outages. This lesson shows that relying solely on the electric energy market and balancing services The profit of the market cannot attract enough capital to invest in the construction of unit capacity, and cannot guarantee sufficient reserve capacity during the peak load period. Therefore, it is necessary to add additional capacity to the electricity market and strengthen the incentives for unit investment.

[0004] The countries operating the capacity market at this stage mainly include the regional power cooperation organization PJM composed of three power companies in the United Kingdom and the United States (Pennsylvania, New Jersey and Maryland), the independent system dispatching organization ISO-NE in New England, and the ISO-NE independent system dispatching organization in New York. -NY) and the four Nordic countries (Sweden, Denmark, Norway, Finland), however, the previous power investment decision-making methods only considered the profit of the electric energy market, and did not involve the incentives of the capacity market
