为了适应可用资源的电力消耗性质和模式的变化，公用事业公司多年来引入了多种费率结构。本文开发了一种综合优化方法，解决主要是商业建筑的建筑物利用率结构的多样性。它包括一组通用约束，可用于任何具有建筑负载、可再生能源和电池储能系统 (BESS) 的系统。为公用事业公司可以在商业建筑上执行的每种类型的费率结构制定成本函数。开发了一种新颖的算法来应用优化模型并通过使用适当的成本函数生成所需的最佳输出。获得并比较了几种建筑荷载和率结构类型的结果。结果表明，与具有固定能源费率的建筑物相比，添加 BESS 对于负载系数较低和临界峰值定价 (CPP) 费率结构的建筑物更有效。这些结果可以帮助客户决定其可再生能源发电和能源存储的不同费率结构选项和资源规划。
To accommodate the changes in the nature and pattern of electricity consumption with the available resources, utility companies have introduced a variety of rate structures over the years. This paper develops a comprehensive optimization method that addresses the diversity of utility rate structures of buildings principally commercial buildings. It includes a general set of constraints that can be used for any system with a building load, a renewable source, and a battery energy storage system (BESS). A cost function is formulated for each type of rate structure that can be exercised by a utility on a commercial building. A novel algorithm is developed to apply the optimization model and generate the desired optimal outputs by using the appropriate cost function. The results for several building loads and rate structure types were obtained and compared. The results exhibit that adding BESS is more effective for buildings with lower load factor and Critical Peak Pricing (CPP) rate structures in comparison to the buildings with flat energy rates. These results can help a customer with deciding on the different rate structure options and resource planning of their renewable generation and energy storage.
