High levels of non-dispatchable photo-voltaic (PV) generation integrated with the grid may disrupt its operation. Aligning the PV panels to follow local building demand can partially elevate this. We investigate the economic viability of alignment for buildings owners and grid utility. A bi-level optimization framework is built to determine the design of a building rooftop PV system. An upper-level optimizer selects panel design parameters to lower either cost or grid electricity imports of the lower-level optimization. The lower-level energy-economical model optimization sizes the panels to minimize building electricity cost given building demand, given grid pricing, available roof area, and other factors. A case study of commercial building archetypes in Vancouver BC finds that at the price of $1.25\$\mathrm{CAD}/{\mathrm{W}}_{\mathrm{p}}$ (50% reduction of current prices) PV is profitable. For all archetypes profitable alternative grid-friendly designs were found, however, for some buildings large increases in peak power are observed. For some archetypes, a profitable alternative was found that lowers the overall electricity imports (between 4 and 7%) and limits impacts on peak power exports (below 125% of original peak import). Our future work will look into the uncertainty and sensitivity of the framework, technology improvements, and alternative economical models.

与电网集成的高水平不可调度光伏 (PV) 发电可能会中断其运行。调整光伏电池板以满足当地建筑需求可以部分提升这一点。我们调查了建筑物所有者和电网公用事业对齐的经济可行性。构建了一个双层优化框架来确定建筑屋顶光伏系统的设计。上级优化器选择面板设计参数以降低下级优化的成本或电网电力输入。考虑到建筑需求、电网定价、可用屋顶面积和其他因素，较低级别的能源经济模型优化了面板的尺寸以最小化建筑电力成本。卑诗省温哥华商业建筑原型的案例研究发现，以$1.25\$\mathrm{计算机辅助设计}/{\mathrm{宽}}_{\mathrm{磷}}$（当前价格降低 50%）光伏是有利可图的。对于所有原型，都发现了有利可图的替代电网友好设计，但是，对于某些建筑物，观察到峰值功率大幅增加。对于某些原型，发现了一种有利可图的替代方案，可降低总电力进口（4% 至 7%）并限制对峰值电力出口的影响（低于原始峰值进口的 125%）。我们未来的工作将研究框架、技术改进和替代经济模型的不确定性和敏感性。
