摘要
建设含高比例新能源的新型电力系统对电力系统的调节灵活性提出新的要求。为充分挖掘需求侧灵活负荷资源,部分省份发布需求响应方案以引导电力用户参与削峰需求。需求侧中,高耗能工业负荷具备负荷单体容量大,功率可控性强等优点,但其参与需求响应受限于负荷正常生产需求与缺乏最大化响应收益控制策略。由此,该文以电解铜工业负荷为例,提出面向需求侧市场化响应交易细则的高耗能负荷功率控制策略。首先,分析电解铜负荷工艺流程环节功率调节可行性并建立对应功率控制模型;建立电解铜工艺流程资源任务网络(resourcetask network,RTN)模型以描述负荷生产周期内生产状态,通过物料数量明确负荷功率调控边界。基于四川省需求响应实施方案交易细则,明确负荷响应收益结算机制及有效响应约束;考虑功率调控产生的额外成本,提出满足负荷生产安全与有效响应约束的最大化负荷响应收益的功率控制策略;最后,在不同情景下进行仿真,相较于仅满足中标响应需求,该文功率控制策略能够提升响应收益16%以上,并且在较长时间尺度响应中能够最大程度满足响应需求,验证该文功率控制策略的有效性,为工业负荷参与需求响应提供一种可行方案。
The development of a new power system with a high proportion of renewable energy sources presents new requirements for the flexibility of the power system.In order to fully tap into the flexible load resources on the demand side,some provinces have released demand response programs to encourage electricity users to participate in peak demand reduction.High-energy-consuming industrial loads have advantages such as large individual capacities and strong power controllability.However,their participation in demand response is limited by normal production needs and a lack of strategies to maximize response benefits.Therefore,this paper proposes a power control strategy for high-energy-consuming loads,using electrolytic copper as an example,in a demand-side market response plan.Initially,the feasibility of power adjustment in the electrolytic copper process is analyzed and a power control model is established.A resource task network(RTN)model is established for the electrolytic copper process to describe production states within the load production cycle and power control boundaries are determined based on material quantities.Based on the demand response implementation plan in Sichuan Province,the mechanism is clarified for calculating load response benefits and constraints.Considering additional costs incurred by power control,a method is proposed to calculate the cost of load participation in response.A power control strategy maximizing load response benefits while considering additional costs,production safety and effective response constraints is proposed.Finally,simulations are conducted under different scenarios,demonstrating that the power control strategy in this paper can increase response benefits by over 16%compared to meeting only the contracted response demand.Additionally,it effectively meets response demand over longer time scales,validating the effectiveness of the proposed power control strategy and providing a feasible solution for industrial load participation in demand response.
