内嵌可行性测试的输电权市场拍卖收益权分配方法
An Embedded Feasibility Testing Method for Auction Revenue Rights Allocation in Transmission Rights Markets
【目的】 为了保证拍卖收益权的分配结果在实际电网中具有物理可执行性，拍卖收益权的分配结果需要满足可行性测试。传统的基于灵敏度因子的可行性校验算法使得拍卖收益权的分配结果依赖于线路的次序，从而影响削减结果的公平性。为此，提出了一种内嵌可行性测试的拍卖收益权分配方法。【方法】 首先，提出拍卖收益权的分配原则和申报方式，保障参与者的基本用电权益。然后，提出一种内嵌可行性测试的拍卖收益权分配算法。该算法以最小化用户总申请容量的削减量为目标，考虑线路潮流约束，建立拍卖收益权分配模型并求解。最后，基于IEEE 5节点系统，将所提算法与采用传统可行性校验的分配算法进行对比。【结果】 结果表明，所提方法相比传统方法在节点边际电价（locational marginal pricing，LMP）机制下总削减量减少可达25.0%，线路利用率提高可达7.2个百分点；在负荷侧统一电价机制下总削减量减少了20.9%，线路利用率提高了9.2个百分点。【结论】 所提方法可以提升拍卖收益权分配的公平性，降低总削减量，提高线路利用率。
[Objective] In ensuring the physical feasibility of auction revenue right （ARR） allocation in actual power grids， feasibility tests must be satisfied. Traditional post-feasibility verification algorithms based on sensitivity factors make ARR allocation results dependent on line sequences， which affects the fairness of the results. This study proposes an ARR allocation method with embedded feasibility testing.[Methods] First， ARR allocation principles and application methods are proposed to safeguard the basic electricity rights of the participants. Subsequently， an ARR allocation algorithm with embedded feasibility testing is developed. This algorithm aims to minimize the total reduction in the users' requested capacity while considering line-flow constraints， by establishing and solving an ARR allocation model. Finally， based on the IEEE 5-bus system， the proposed algorithm is compared with the traditional post-feasibility verification allocation algorithm.[Results] Compared with traditional methods， the proposed method decreased total capacity reduction by up to 25.0% and increased line utilization rate by up to 7.2% under the locational marginal pricing （LMP） mechanism. Under the load-side uniform pricing mechanism， total capacity reduction decreased by 20.9% and line utilization rate increased by 9.2%.[Conclusions] The results show that the proposed method improves the fairness of ARR allocation， decreases total capacity reduction， and increases line utilization rate.

在推进我国新一轮电力体制改革和建设全国统一电力市场的背景下,为了打破省间壁垒,缓解现行区域电力市场部分省份因备用容量不足和源荷逆向分布而存在的电力紧缺或“三弃”问题,引入备用共享机制和联络线协调优化的运行方式,构建了包括安全约束机组组合模型和安全约束经济调度模型在内的区域电力现货市场电能与备用联合出清模型。通过考虑备用共享的区域电力现货市场电能与备用联合出清,实现了电力资源在更大范围的优化配置,有效提高了系统运行的经济性和可靠性。以两个互联的IEEE 30节点系统模拟区域内两省间电力市场交易,验证了所提模型的正确性和有效性。
Under the background of promoting our country’s new round of electric power system reform and building the national unified electricity market, in order to break down inter-provincial barriers and alleviate the power-shortage, abandoned water, wind curtailment and discarded light in some provinces of regional electricity market due to the lack of reserve capacity and the inverse distribution of energy and load, this paper introduces reserve sharing mechanism and coordinated optimization of tie-line, constructs a combined clearing model of energy and reserve for regional electricity spot market, including the security constraints of unit combination and security constraints of economic dispatch. Through combined clearing of energy and reserve for regional electricity spot market considering reserve sharing, the optimal allocation of power resources in a wider range is realized, and the economy and reliability of system operation are improved effectively. Two interconnected IEEE 30-node systems are used to simulate the electricity market transactions between two provinces in the region, and the correctness and effectiveness of the proposed model are verified. |

期货交易存在保证金和强行平仓制度,全市场背景下电力期货交易制度的特殊性在一定程度上影响着发电企业收益。考虑负荷变化,利用电力期货交易规避电价波动造成的发电侧盈亏风险,构建了一种发电企业全市场收益优化模型。首先,搭建含现货、远期合同和期货合约的电力市场交易架构;其次,以发电企业售电收益最大为目标,逐级搭建含现货、远期合同和期货合约的发电企业收益模型,并给出相应求解算法;最后,采用6个发电企业构成的无阻塞电力市场进行仿真模拟,对收益模型的合理性与有效性进行了验证。结果表明:负荷侧波动导致电价明显波动,电力期货的引入能提高电价稳定性,提高发电企业利润,将发电企业利润损失风险转移到期货市场中,并且边际成本越大的发电企业利润提高越明显;在一定的期货与现货电量配比范围内,配比越大,发电企业利润提高越多,但超过范围后,期货保证金利息亏损变多,发电企业利润反而减少。
Margin and forced liquidation systems in futures trading affect the income of power generation companies to a certain extent in the market context. Considering the changes in load, this study uses electricity futures trading to avoid the profit and loss risk of power generation caused by electricity price fluctuations and constructs a market-wide revenue optimization model for power generation companies. First, we construct a trading structure for the electricity market that includes spot, forward, and futures contracts. Second, with the goal of maximizing revenue from electricity sales of power generation companies, the income model of power generation companies, including spot, forward, and futures contracts, is built step-by-step, and the corresponding solution algorithm is given. Finally, a non-blocking power market comprising six power generation companies is used for the simulation, and the rationality and effectiveness of the revenue model are verified. The results show that load fluctuations lead to obvious fluctuations in electricity prices, and the introduction of electricity futures can improve the stability of electricity prices and the profits of power generation companies and transfer the risk of profit loss of power generation companies to the futures market. The increase in the profits of power generation companies with greater marginal costs is more obvious. Within a certain range of futures and spot electricity ratios, the larger the ratio, the greater the profits of the power generation company; however, after exceeding the range, the loss of futures margin interest increases, which causes the profits of power generation companies to decrease. |

随着电力市场化改革不断深化,电力系统开放程度不断上升,电力系统输电阻塞及对应产生的阻塞费用不断增加。如何有效、合理分配阻塞费用是实现电力系统稳定运行,保障电力市场有序竞争中的关键一环。文章从国外典型电力市场阻塞费用分配办法出发,总结国内现货市场阻塞费用分配机制存在的共性问题,如目前中长期合同结算参考点仍然设置在用户的统一结算点。文章结合南方(以广东起步)区域电力现货市场阻塞费用分配机制现实情况,通过算例理清不同发展阶段阻塞费用分配机制的演化逻辑,为完善相关机制建设提供参考。文章建议应放开中长期结算参考点的选择,使用户与发电侧自行协商,并逐步放开用户侧结算价格的限制,使得节点电价发挥其市场信号的作用。
Under the deepening of China’s power market reform, the deregulation of the power system is resulting in increasing transmission congestion and corresponding congestion revenue. Allocating congestion revenue effectively and reasonably is critical for achieving stable operation of the power system and ensuring orderly competition in the electricity market. According to the experience of foreign developed power market, this paper firstly summarizes the existing common problem of domestic congestion revenue allocation such as merely using the unified settlement price of users as the reference settlement price of medium and long term contract, which is followed by an analysis of the actual practice commenced in Guangdong using the numerical example to further demonstrate the inner evolution logic, while providing relevant suggestions for future development. The paper suggests that the medium and long term contract settlement reference price should be decided by both contract parties on their own, and restriction on user’s settlement price should be lifted so that the nodal price can effectively send market signal. |
