摘要

考虑风电的不确定性及系统供需互动

提出了基于卖方灵活电力合约的规定浮动电力区间的风电合同。推导购售电双方参与竞价交易及合同交易的效用模型

得到基于合同交易机会成本定价下各自可接受的合同价格

并通过场外协商经系统安全校核完成合同制定。风电商可在合同交易的同时参与竞价市场交易

或利用发、用电权交易协议组成供需多方联盟减弱风电不确定性造成的效用降低。算例采用蒙特卡洛法模拟求解

验证了所提方法的有效性

分析了风电合同价格的影响因素

证明了风电合同能够提升交易各方的效益。

Abstract

By taking uncertainties of wind power and supply-demand interaction into account

a wind power contract with a limited floating range of power exchange based on seller-side flexible electricity contract is proposed. The utility functions of both purchasing and selling sides in the spot market and contract trading are derived

and acceptable price ranges of contract based on the opportunity costs of contract trading are generated. The contract is finally formulated by over-the-counter negotiation and system security check. The wind power producer can participate in the bidding market while signing contract with customers

or mitigate the utility reduction from wind power uncertainties through multi-part alliance formed in the power generation or consumption rights trading. The numerical example is solved by the Monte Carlo simulation. The effectiveness of the method is verified

and the factors affecting the contract price are analyzed. Results show that the contract trading of wind energy can improve the profitability of all trading participators. This work is supported by State Grid Corporation of China (No. DZN17201300045).
