在风光火储打捆基地外送价格形成机制尚不明确且暂无可借鉴成熟经验的背景下,对沙戈荒基地外送经济性测算展开分析与讨论.首先考虑以系统运行成本最小为目标搭建了生产运行模拟模型,并基于经营期法和按发电量比例分配原则搭建打捆送电成本电价测算模型.以沙戈荒基地外送某典型工程为例,对基地发电、送电等外送全环节经济性进行了测算.进一步从打捆电源配置、标准煤单价、增配储能、考虑调峰收益、单位造价等几方面分析影响沙戈荒基地发电成本电价的主要因素,并通过比较受端区域燃煤发电基准价与测算的落地成本电价对市场竞争力进行分析讨论.案例的分析结果从经济成本与市场竞争力角度对沙戈荒基地外送工程规划、建设及定价机制设计具有借鉴作用,对全面贯彻落实碳达峰碳中和战略决策,服务能源转型和清洁绿色低碳发展具有重大意义.
Analysis on the Economic and Market Competitiveness of the Base Export Project in the Gobi and Desert Areas of China Considering Multiple Influencing Factors
Under the background of unclear pricing mechanisms for transmitting wind,photovoltaic,storage generation power in combination with thermal power,as well as the lack of mature experience for reference,the economic calculation for base export project in the gobi and desert areas was analyzed and discussed.Firstly,a production operation simulation model with the goal of minimizing operating costs was established,and a bundled cost electricity price calculation model based on the operating period method and principle of allocation ratio of power generation was constructed.Based on this,taking a typical project in the gobi and desert areas as an example,economy of all links such as power generation and transmission for a base was calculated.Furthermore,the main factors affecting the cost electricity price of the base export were discussed from several aspects such as installed capacity ratio of baling power supply,standard coal unit price,increased allocation of energy storage,benefits of peak shaving,and unit cost.Finally,comparing the benchmark price of coal-fired power generation with the calculated cost electricity price in the receiving region,the electricity price competitiveness was analyzed.The result of the case has a reference value for the planning,construction,design of pricing mechanism of base export project in the gobi and desert areas.Meanwhile it is significance for the comprehensive implementation of the carbon peak and carbon neutrality strategy decision-making,serving energy transformation and clean,green,and low-carbon development.
