    A distributed algorithm for managing residential demand response in smart grids

    , Article IEEE Transactions on Industrial Informatics ; Vol. 10, issue 4 , November , 2014 , p. 2385-2393 ; ISSN: 15513203 Safdarian, A ; Fotuhi-Firuzabad, M ; Lehtonen, M ; Sharif University of Technology
    Abstract
    Demand response enabled by time-varying prices can propel the power industry toward a greater efficiency. However, a noncoordinated response of customers may lead to severe peak rebounds at periods with lower prices. In this regard, a coordinated demand response scheme can mitigate concerns about the peak rebounds. This paper presents a system-wide demand response management model to coordinate demand response provided by residential customers. The objective of the model is to flatten the total load profile that is subject to minimum individual cost of customers. The model is first formulated as a bi-level optimization problem. It is then casted into equivalent single-level problems, which... 

    Demand side management for a residential customer in multi-energy systems

    , Article Sustainable Cities and Society ; Volume 22 , 2016 , Pages 63-77 ; 22106707 (ISSN) Sheikhi, A ; Rayati, M ; Ranjbar, A. M ; Sharif University of Technology
    Abstract
    Today, as a consequence of the growing installation of efficient technologies, e.g. micro-combined heat and power (micro-CHP), the integration of traditionally separated electricity and natural gas networks has been attracting attentions from researchers in both academia and industry. To model the interaction among electricity and natural gas networks in distribution systems, this paper models a residential customer in a multi-energy system (MES). In this paper, we propose a fully automated energy management system (EMS) based on a reinforcement learning (RL) algorithm to motivate residential customers for participating in demand side management (DSM) programs and reducing the peak load in... 

    Designing a Proper Residential Demand Response Program To Improve Distribution System Reliability

    , M.Sc. Thesis Sharif University of Technology Sarajpoor, Nima (Author) ; Fotuhi-Firuzabad, Mahmoud (Supervisor)
    Abstract
    In recent years, the pace of increment in electrical energy consumption is getting faster. Establishing new power-plants to keep a balance between generation and consumption not only has a high investment cost but also is a time consuming procedure. Thus, several studies have focused on the demand side management. Residential consumers possess remarkable portion of total electricity consumption. Accordingly, at first, the appropriate residential demand response program is selected based on presented experimental criteria. In the next step, since the network reliability is an important issue to the operators, the impact of implementation of the demand response program is studied on the... 

    Investigation of Demand Response to Changing the Household Electricity Meter from Single Stroke Case to Three Stroke Case; Evidence from Tehran Interior Region 2

    , M.Sc. Thesis Sharif University of Technology Sadeghi, Saeed (Author) ; Vesal, Mohammad (Supervisor)
    Abstract
    This study investigates consumers’ response to changing the household electricity meter from single stroke case to three stroke case. Existence of different prices in different hours during the day is the advantage of three stroke electricity meters compared to single stroke ones. Electricity bill data of 19,742 subscribers, in Tehran Interior Region 2, during the period 1387 to 1393, has been used to evaluate this policy. Subscribers who always use only single stroke electricity meters or three stroke ones are considered as the control group; and subscribers who have experienced electricity meter change during the period are considered as the experimental group. Changing electricity meters... 

    Residential Demand Response Coordination to Enhance Network Reliability

    , M.Sc. Thesis Sharif University of Technology Kabirifar, Milad (Author) ; Fotuhi Firouzabad, Mahmud (Supervisor)
    Abstract
    Residential demand response is an appropriate control tool for improving system reliability. This project intends to establish a model to activate residential demand response to improve distribution network reliability. Two centralized and decentralized models are proposed. The models aim at minimizing the damage cost imposed by load curtailments following unexpected events. In the models, it is supposed that distribution system operator (DSO) and responsive customers already signed a contract authorizing the DSO alters the operation of responsive appliances whenever system reliability is jeopardized. In centralized framework, Responsive customers deliver the technical data of their... 

    Forecasting Residential Natural Gas Consumption in Tehran Using Machine Learning Methods

    , M.Sc. Thesis Sharif University of Technology Khazaei, Armin (Author) ; Maleki, Abbas (Supervisor)
    Abstract
    According to increasing energy demand in Iran and the world, the role of natural gas as a relatively clean and cost-effective source has received more attention. Given the high share of the residential sector in the country's natural gas consumption, providing a model for forecasting the demand of this sector is of great importance for policy makers and decision makers in this field. In the present study, we employ three popular methods of machine learning, support vector regression, artificial neural network and decision tree to predict the consumption of natural gas in the residential sector in Tehran according to meteorological parameters (including temperature, precipitation and wind... 

    Implementation of Load Studies for Residential Customers of Tehran Electricity Distribution Company based on Their Regional Characteristics and Welfare Levels

    , M.Sc. Thesis Sharif University of Technology Mohabbatian, Omid (Author) ; Hajipour, Ehsan (Supervisor)
    Abstract
    Distribution companies typically use ADMD and coincidence factors to calculate aggregated loads. However, these factors have a significant impact on the selection of the optimal capacity of distribution network equipment; But so far, comprehensive studies at the level of single customers have not been implemented on the calculation of these factors. In this work, a comprehensive study has been conducted on residential customers in Tehran and the consumption data of 2121 residential customers, which were recorded during the summer of 2020, are used. The data were collected in two separate sets to investigate the effect of two factors: the type of cooling load and the welfare level of...

Authors proposed a comprehensive cost and benefit analysis to optimize these elements and apply Reinforcement Learning (RL)... 

    Applying reinforcement learning method to optimize an Energy Hub operation in the smart grid

    , Article IEEE Power and Energy Society Innovative Smart Grid Technologies Conference, ISGT 2015, 18 February through 20 February 2015 ; 2015 ; 9781479917853 (ISBN) Rayati, M ; Sheikhi, A ; Ranjbar, A. M ; Sharif University of Technology
    Abstract
    New days, the concepts of 'Smart Grid' and 'Energy Hub' have been introduced to improve the operation of the energy systems. This paper introduces a new conception entitling Smart Energy Hub (S. E. Hub), as a multi-carrier energy system in a smart grid environment. To show the application of this novel idea, we present a residential S. E. Hub which employs Reinforcement Learning (RL) method for finding a near optimal solution. The simulation results show that by applying the S. E. Hub model and then using the proposed method for a residential customer, running cost is reduced substantially. While, comparing with the classical ones, the RL method does not require any data about the...

    Abstract
    Severe peak rebounds are likely in absence of a system-wide coordination among customers participating in demand response programs. This paper aims to establish a decentralized system-wide framework to coordinate demand response of residential customers in a smart grid. The objective of the framework is to modify system load profile provided that customers' payments are minimized, and their comfort and privacy are preserved. Home load management (HLM) modules, embedded in customers' smart meters are autonomous agents of the framework. The energy service provider iteratively exchanges load information with HLM modules in the hope of achieving his desired load profile. In each iteration, the...
