考虑源网荷储效益提升的电力现货市场出清优化模型研究

随着我国在“双碳”目标背景下电力现货市场的发展，以风电、光伏等代表的可再生能源将参与到现货市场出清，由于可再生能源的波动性和不确定性，需要通过需求侧响应和储能间的协调，在保证电网调节灵活性的前提下实现市场多主体效益提升，因此开展考虑源网荷储效益提升的电力现货市场出清优化策略研究。考虑参与日前出清阶段各方的效益，将电网不同峰谷差的调节需求纳入到竞价过程中，提出考虑源、网、荷、储收益分配的现货交易体系；为保证系统低碳运行，考虑供能侧的碳排放权交易，建立基于供能侧、储能侧，电网侧、需求侧多方效益协调的电力现货市场出清优化模型，通过算例仿真分析验证所提模型的有效性和优越性。

Clearing optimization model of power spot market Incorporating generation, network, load and Storage benefit improvement

With the development of power spot market under the background of the goals of carbon peak and carbon neutrality, renewable energy represented by wind power and photovoltaic will participate in the spot market. Due to the volatility and uncertainty of renewable energy, it is necessary to improve the multi benefits of the market on the premise of ensuring the flexibility of power grid regulation through the coordination operation of demand side response and energy storage. Therefore, this paper researches the clearing optimization strategy of power spot market based on multi-party benefit improvement and carbon peak and carbon neutrality. Firstly, considering the benefits of all parties involved in the day ahead clearing stage, the regulation requirements of different power grid peak valley are included in the bidding process. A spot trading system considering energy supply, energy storage, grid and demand side revenue distribution is proposed. Then, In order to ensure the low-carbon operation of the system, the clearing model of power spot market based on the coordination and optimization of energy supply, energy storage, grid and demand side benefits is established based on carbon emission trading on the energy supply side. Finally, case study is performed to verify validity and superiority of the model.
