The spot market of electricity makes electricity return to the commodity attribute, which makes the market play an increasingly prominent role in the allocation of power resources. The electricity-trading mode has become an important part of the power market construction and power reform because it is conducive to promoting the consumption of new energy power generation and realizing the optimal allocation of power resources. This paper constructs technical routes for a thermal power unit in Shandong Province. The first is waste heat recovery, refrigeration scheme based on the voltage shrink heat pump and the second is deep peak shaving scheme based on the electric boiler and energy storage tank. The technical transformation scheme is providefor the thermal power unit to participating in the spot power market. The result show that energy supply capacity of the system increased by 48 MW, the cooling capacity increased by 32 MW, and the peak shaving capacity of the unit increased by 9%. In addition, the financial internal rate of return (before tax) of the project is 30.25%, and the payback period (before tax) is 4.1 years, with good profitability.

电力现货市场让电力回归商品属性,使得市场在电力资源配置中的作用日益突出。由于这一电力交易模式有利于促进新能源发电消纳,实现电力资源的优化配置,因此成为电力市场建设和电力改革的重要一环。以山东省某热电联产机组为例,构建了基于电压缩式热泵的余热回收及制冷方案与基于电锅炉耦合冷热双蓄水储能的深度调峰方案,为该机组参与电力现货市场提供了可行的技术改造方案。研究结果表明:改造后系统供热能力提升48 MW,供冷能力提升32 MW,机组调峰能力提升9%;项目财务内部收益率(税前)30.25%,投资回收期(税前)4.1年,具有较好的盈利能力。

电力现货市场让电力回归商品属性,使得市场在电力资源配置中的作用日益突出。由于这一电力交易模式有利于促进新能源发电消纳,实现电力资源的优化配置,因此成为电力市场建设和电力改革的重要一环。以山东省某热电联产机组为例,构建了基于电压缩式热泵的余热回收及制冷方案与基于电锅炉耦合冷热双蓄水储能的深度调峰方案,为该机组参与电力现货市场提供了可行的技术改造方案。研究结果表明:改造后系统供热能力提升48 MW,供冷能力提升32 MW,机组调峰能力提升9%;项目财务内部收益率(税前)30.25%,投资回收期(税前)4.1年,具有较好的盈利能力。

The spot market of electricity makes electricity return to the commodity attribute, which makes the market play an increasingly prominent role in the allocation of power resources. The electricity-trading mode has become an important part of the power market construction and power reform because it is conducive to promoting the consumption of new energy power generation and realizing the optimal allocation of power resources. This paper constructs technical routes for a thermal power unit in Shandong Province. The first is waste heat recovery, refrigeration scheme based on the voltage shrink heat pump and the second is deep peak shaving scheme based on the electric boiler and energy storage tank. The technical transformation scheme is providefor the thermal power unit to participating in the spot power market. The result show that energy supply capacity of the system increased by 48 MW, the cooling capacity increased by 32 MW, and the peak shaving capacity of the unit increased by 9%. In addition, the financial internal rate of return (before tax) of the project is 30.25%, and the payback period (before tax) is 4.1 years, with good profitability.
