Optimization of Residential Load Consumption during Energy Peaks using Smart Metering

Abstract

Abstract.Recently smart demand side management (DSM) is a very important tool that permits customers to take right decisions for their energy consumption and helps the energy utilities to decrease the over load demand and reshape the load curve. This paper proposes an optimized DSM technique based on smart metering uses different techniques such as load shifting and peak clipping to minimize domestic power consumption especially during load peaks. A new optimization technique (Bat Algorithm) is applied on proposed system and then compares results with other optimization techniques (Genetic Algorithm and Interior point Algorithm) to optimize the minimum consumption during peak hours according to load type. A control algorithm is applied to the proposed system to achieve the load shifting and load clipping according to the optimization results.

Smart DSM to optimize residential load consumption during energy peaks

“…Figure .2. proposed system with control action [10] In a lower level, Figure .2 shows the categorization of loads inside consumers' home according to loads priority for any of the classes. Loads are categorized into three types: A-Base line loads whose power consumption must be continuous for all time, such as lightning, refrigerator and fans, B-reducible loads, whose power consumption can be decreased for some time periods, such as air conditioning and Water heater, Cdeferrable loads, whose operation or charging time can be deferred, such as washing machines, Electrical oven and Microwave oven [12].…”

“…This can be achieved through the following objective equations [9] C: Price parameter is calculated using Egyptian Electric utility and Consumer's Protection. Price parameter in this paper has varied in different periods around the 24 hours as the first period (from 8AM up to 2PM and from 2AM up to 8AM are OFF Peak periods with reduced tariff) and the second period (from 2PM up to 8PM and from 8 PM up to 2AM) are Over Peak periods with another, which applies monthly tariff as an hourly tariff with scaled results [10,15]. n: no.…”
