摘要/Abstract

摘要：

针对沿海工业园区及靠岸船舶供电负荷惯性薄弱、需求量波动大、响应性较差等问题,提出一种考虑气热能延迟特性的综合能源系统(Integrated energy system,IES)日前-日内调度策略,实现多能流的解耦与分配。在工业负荷出现波动时,日内调度根据每个时刻预测负荷和日前预测负荷的差值,考虑能流多种转化途径,以优先保持电负荷平衡的情况下最大限度地满足冷热负荷平衡为调度原则,建立能流分配的判断指标,对日前计划进行修正。策略中计及了气热能转换设备出力的延迟特性,在延迟时间内补充了能量损失。通过算例仿真分析,验证了所提复合调度策略能够利用各类能流的耦合互补关系,平抑冷热电负荷波动,减小调度误差,提高综合能源系统的能量利用效率和经济效益。

Abstract:

In view of the problems of weak power supply load inertia, large demand fluctuation and poor responsiveness of coastal industrial parks and berthing ships, a compound scheduling strategy considering gas and heating energy delay characteristics is proposed based on IES(Integrated energy system), which is divided into day-ahead and intraday phases, realizing adaptive decoupling and distribution of energy flow. When the industrial load fluctuates, the various energy flow conversion ways are considered by intraday dispatching according to the difference between the predicted load at each time and the predicted load in the day ahead, thus the judgment index of energy flow distribution is established, and the day ahead plan is revised, aiming to meet the dispatching principle that keep the cold and hot load balance as much as possible under the condition of priority to maintain the electric load balance. In the strategy, the delay characteristics of the output of the gas and heating energy conversion equipment are considered, and the energy loss is supplemented in the delay time. Finally, through the simulation result of a given example, it is verified that the coupling and complementary relationship of various energy flows can be fully utilized through the implement of proposed compound scheduling strategy. Consequently, the fluctuation of the cooling, heating and power load, scheduling error and the energy utilization efficiency and economic benefits of IES can be optimized.

Key words: Integrated energy system, scheduling strategy, energy flow control and distribution, delay characteristics, balance of cooling, heating and power load
