【摘要】：随着中国电力市场的发展与完善以及电网新技术的采用,电网规划尤其是输电网规划面临着新问题和新挑战。为了应对上述情况,文中在确定性规划准则和概率性规划准则的基础上,提出了一个在电力市场环境下应用于输电网中长期规划的多场景混合性规划模型。该模型整合了确定性规划准则和概率性规划准则的相关约束和参数,包括:柔性约束、投资费用、电力供应、购电费用、时间成本、故障发生概率、可靠性成本、期望缺供电量(EENS)以及缺电时间期望(LOLE)等。同时,通过定义多个场景来模拟电力系统的负荷水平,并考虑电力市场的因素,将输电网规划问题转为混合整数线性规划问题,通过直流潮流模型和商业优化软件CPLEX,寻找输电网最优规划方案。最后,通过与传统规划模型的对比和实际电网算例,验证了该模型的有效性、灵活性和经济性。
[Abstract]:With the development and perfection of Chinese power market and the adoption of new power grid technology, power network planning, especially transmission network planning, is facing new problems and challenges. In order to deal with the above situation, based on the deterministic planning criteria and probabilistic planning criteria, a multi-scenario hybrid planning model is proposed for medium and long-term power transmission network planning in the power market environment. The model integrates the constraints and parameters of deterministic programming criteria and probabilistic planning criteria, including: flexibility constraints, investment costs, power supply, power purchase costs, time costs, probability of failure, reliability costs. Expect short power supply (EENS) and electricity shortage time expectation (Lole), etc. At the same time, by defining several scenarios to simulate the load level of the power system and considering the factors of the power market, the transmission network planning problem is transformed into a mixed integer linear programming problem. Through DC power flow model and commercial optimization software CPLEX, the optimal plan of transmission network is found. Finally, the validity, flexibility and economy of the model are verified by comparison with the traditional programming model and practical examples.
