按需收费的最优恒温器规划和最优电价

Optimal Thermostat Programming and Optimal Electricity Rates for Customers with Demand Charges

Reza Kamyar, Matthew M. Peet

摘要:

我们考虑耦合问题的最优恒温器规划和最优定价的电力。我们的框架由一个用户和一个供应商(受监管的公用事业)组成。供应商为用户设定价格,用户为总消耗的能量(每千瓦时,包括高峰和非高峰费率)和一个月的消耗高峰费率(按需收费)(每千瓦时)支付费用。供应商的电力成本是基于容量成本(\$/千瓦)和燃料成本(\$/千瓦时)的组合。在最佳恒温器编程问题中,用户在保持在预定义的温度范围内的同时最小化支付的电费。用户可以使用建筑物内部结构的热容形式的能量存储。供应商制定的价格旨在最大限度地减少生产电力的总成本,同时满足用户的需求。为了解决用户的问题,我们使用一个变种的动态规划。为了解决供应商的问题,我们使用下降算法加上我们的动态规划代码-产生最佳的高峰期,非高峰期和需求价格。我们表明,热存储和最佳的恒温器编程可以减少电费使用当前的公用事业价格从公用事业亚利桑那州公共服务(APS)和盐河项目(SRP)。此外,我们得到最优的公用事业价格,导致发电成本和电费的显着降低。

英文摘要:

We consider the coupled problems of optimal thermostat programming and optimal pricing of electricity. Our framework consists of a single user and a single provider (a regulated utility). The provider sets prices for the user, who pays for both total energy consumed (\$/kWh, including peak and off-peak rates) and the peak rate of consumption in a month (a demand charge) (\$/kW). The cost of electricity for the provider is based on a combination of capacity costs (\$/kW) and fuel costs (\$/kWh). In the optimal thermostat programming problem, the user minimizes the amount paid for electricity while staying within a pre-defined temperature range. The user has access to energy storage in the form of thermal capacitance of the interior structure of the building. The provider sets prices designed to minimize the total cost of producing electricity while meeting the needs of the user. To solve the user-problem, we use a variant of dynamic programming. To solve the provider-problem, we use a descent algorithm coupled with our dynamic programming code - yielding optimal on-peak, off-peak and demand prices. We show that thermal storage and optimal thermostat programming can reduce electricity bills using current utility prices from utilities Arizona Public Service (APS) and Salt River Project (SRP). Moreover, we obtain optimal utility prices which lead to significant reductions in the cost of generating electricity and electricity bills.
