摘要:

现代化农业园区温室环境系统与光伏发电系统易出现“源荷错峰”运行问题。为此,提出一种考虑农作物生长需求的农业园区微能源网(agricultural park microgrid,APMG)参与配电市场出清的能量管理双层优化模型,以实现农作物快速生长与多类型能源高效利用。双层模型中,上层模型以APMG运营成本最小为优化目标,在考虑配电市场电价、光伏发电等因素的基础上,计算农业园区温室环境系统的最佳能量管理策略模型;下层模型为配电市场出清模型,其目标为实现配电网最佳电能配置,并得到出清价格。进一步,利用自适应交替方向乘子法求解双层模型。最后,以IEEE-12节点配电系统和66节点内蒙古某县农村配电系统为例,验证所提模型及方法的有效性。算例结果表明,该模型可有效降低农业园区23.2%的用能成本,同时还能降低配电网用户6.2%购电费用。

Abstract:

Greenhouse environmental systems and photovoltaic power plants in modernized agricultural parks are prone to “source-load peaking” operation problems. To address this issue, this study proposes a two-layer optimization model for energy management of the agricultural park micro energy network (APMEN) participating in distribution market clearing, considering the crop growth characteristics to achieve rapid growth of crops and efficient use of multiple types of energy. The upper-layer model calculates the optimal energy management strategy for the greenhouse environmental system of the agricultural park, with the objective function of minimizing the operating cost of the APMEN, considering the accessory market tariff and photovoltaic power generation. The lower-layer model corresponds to the distribution market-clearing model, which aims to achieve optimal power allocation in the distribution network. Furthermore, the two-layer model is solved using the adaptive alternating direction multiplier method. Finally, the IEEE 12-node distribution system and 66-node Inner Mongolia Autonomous County rural distribution system were used as examples to verify the effectiveness of the proposed model and method. The results show that the model can effectively reduce the energy cost of agricultural parks by 23.2% and the power purchase cost of distribution network users by 6.2%.
