针对综合能源系统供热侧源荷时序不匹配、热力管网动态特性利用不足以及建筑热惯性难以主动参与调度的问题,本文提出一种计及管网与建筑虚拟储能显式调度的MPC-MILP滚动优化方法。构建包含热电联产机组、燃气锅炉、电热泵、太阳能集热器、实体储热、5.0 km供热管网及工业厂房、住宅小区、商业楼宇三类建筑热用户的源-网-荷-储系统;采用有限差分PDE描述管网传输延迟与沿程散热,采用双节点RC模型描述建筑室温与墙体温度动态。在热平衡中引入管网和建筑虚拟储能等效充放热功率,并将其调用量反馈至供水温度扰动和建筑实际得热量,使虚拟储能调度与物理热状态形成闭环。算例结果表明,系统热负荷满足率达到100%,总运行成本为65441.2元;虚拟储能最大放热功率为369.0 kW,最大充热功率为1000.0 kW,峰段平均放热194.9 kW,谷段平均充热603.1 kW。按日内实际调用量统计,TES实体储能、管网虚拟储能和建筑虚拟储能分别为1130.6、1940.7和6058.1 kWh,三类建筑室温均处于舒适边界内。等效折算结果表明,利用管网与建筑热惯性可减少约4770.2 kWh新增实体TES等效配置需求,并形成约217.0万元的潜在初投资节约。结果验证了两类热惯性资源作为受约束虚拟储能参与MPC调度的可行性、数值可靠性与工程经济价值。
To address the temporal mismatch between heat supply and demand
insufficient utilization of district-heating-network dynamics
and the difficulty of actively incorporating building thermal inertia into dispatch
this paper proposes an MPC-MILP rolling optimization method with explicit scheduling of pipeline and building virtual energy storage. A source-network-load-storage integrated energy system is established
including combined heat and power units
gas boilers
electric heat pumps
solar collectors
physical thermal energy storage
a 5.0 km district heating pipeline
and three types of heat users: industrial buildings
residential communities
and commercial buildings. A finite-difference PDE model is used to describe pipeline transmission delay and heat loss
while a two-node RC model is adopted to characterize indoor and wall temperature dynamics. Equivalent charging and discharging powers of pipeline and building virtual energy storage are introduced into the heat balance and fed back to the physical thermal states. Case results show that the heat-load satisfaction rate reaches 100%
and the total operating cost is 65441.2 yuan. The maximum virtual discharging and charging powers are 369.0 kW and 1000.0 kW
respectively
with an average discharging power of 194.9 kW during peak periods and an average charging power of 603.1 kW during valley periods. In terms of actual daily utilization
the physical TES
pipeline virtual energy storage
and building virtual energy storage are 1130.6
1940.7
and 6058.1 kWh
respectively
while all indoor temperatures remain within comfort limits. Equivalent conversion indicates that
under the assumed investment parameters
using pipeline and building thermal inertia can reduce the equivalent demand for newly installed physical TES by about 4770.2 kWh and provide a potential initial-investment saving of about 2.17 million yuan. The results verify the feasibility
numerical reliability
and engineering economic value of incorporating these two thermal inertia resources as constrained virtual energy storage in MPC-based heat dispatch
