摘要

新能源发电侧大规模应用储能技术会改变电网公司收益

合理安排电网公司在各方能量市场的购电是提升经营效益的有效方案。根据储能系统在新能源电站的容量优化配比方案提出了基于新能源-储能联合系统的购电模型

并考虑中长期购电业务及现货市场购电业务

建立基于条件风险价值的电网公司购售电决策模型;以购售电利益最大、风险损失最小为目标

研究购电策略及有无储能对收益的影响。算例仿真结果表明

新能源上网电价低于火电电价时

新能源电站大规模应用储能技术将为电网公司带来非常可观的收益。

Abstract

The large-scale application of energy storage technology on the new energy generation side will change the income of power grid company. Reasonable arrangement of the power grid in the purchase of electricity in various energy markets is an effective solution to improve operating efficiency. The power purchasing model based on the combined system of new energy-energy storage is proposed in accordance with the capacity optimization ratio scheme of the energy storage system in the new energy power station and

with consideration of the medium-and-long-term power purchase business and the spot market

the power trading strategy model based on value-at-risk is set up. With maximum benefit of purchasing and selling powerandminimumrisklossastarget

thepowerpurchasestrategyandtheimpactofenergystorageonrevenue are studied. The simulation results of the calculation examples show that

in case the on-grid electricity price of new energy is lower than that of thermal power

the large-scale application of energy storage technology in new energy power stations will bring considerable benefits to the power grid company.
