摘要

随着源网荷储一体化建设的不断推进，工业园区对多能协同、源网荷储优化调度提出了更高要求。构建了一个综合考虑工业园区电热负荷需求的源网荷储优化调度模型，模型充分反映了热电联产机组的电热耦合可行域，以及不同机组随负荷变化的热耗特性。采用约束整数规划求解器（SCIP）对光伏、火电、储能与电网购电进行了非线性混合整数优化计算。计算结果表明：在典型日内，火力发电功率占比为65.14%，光伏发电功率占比为20.72%，网购电功率占比为14.45%，储能充电功率占比为2.14%，储能放电功率占比为1.84%；能耗特性较优的火电机组（B型）承担更多的发电、供热的任务（发电功率占比为52%、供热功率占比为97%）。所提分析方法可为工业园区电热负荷需求的源网荷储优化调度方法提供技术参考。

Abstract

With the continuous advancement of the integrated development of source-grid-load-storage

industrial parks have put forward higher requirements for multi-energy synergy and the optimal scheduling of source-grid-load-storage. Comprehensively considering the electrical and thermal load demands in industrial parks

an optimal scheduling model for source-grid-load-storage was proposed. The model fully reflected the electro-thermal coupling feasible region of combined heat and power (CHP) units

as well as the heat consumption characteristics of different units varying with the load. The solving constraint integer program(SCIP) was adopted to conduct nonlinear mixed-integer optimization calculations for photovoltaic power

thermal power

energy storage and grid power purchase. The calculation results indicate that on a typical day

thermal power generation accounts for 65.14%

photovoltaic power generation accounts for 20.72%

grid power purchase accounts for 14.45%

energy storage charging accounts for 2.14%

and energy storage discharging accounts for 1.84%. The thermal power unit(type B) with superior energy consumption characteristics undertakes a greater share of power generation and heating tasks (accounting for 52% of power generation and 97% of heat supply). The proposed analytical method can provide a technical reference for the optimal scheduling of source-grid-load-storage considering electrical and thermal load demands in industrial parks.
