热电联产型微网系统的优化调度研究
摘要：热电联产型微网以分布式电源为基础,在充分利用可再生能源的同时,统一解决了用户的电能与热能需求问题,实现了能源的梯级利用。采用随机模拟技术模拟了风电功率及电负荷需求的随机性,建立了集中控制模式下的孤网系统运行成本最低、供电可靠性最高和综合效益最高的多目标优化调度模型,并提出了优化调度策略。以一个热电联产型微网为例,运用遗传算法优化了各微电源的出力。优化结果验证了本文所提模型和策略的有效性。
Abstract:Based on distributed generation, the combined heat and power micro-grid makes full use of renewable energy sources, solves the unified problem of power and heat demand of users, and realizes the cascade usage of energy. A stochastic technology is proposed to simulate the randomness of wind power and electrical loads, and a multi-objective model of island micro-grid optimal dispatch under the centralized control mode is developed, whose objective functions are to minimize the cost of operation, and maximize the reliability of power supply and the comprehensive benefit. Then a control strategy of micro-grid optimal dispatch under the island mode is presented. Taking a CHP micro-grid system as simulation case, the genetic algorithm is chosen to optimize the micro-source outputs. The results verify the validity of the proposed model and control strategy.
