Kwame Nkrumah University of Science & Technology, Kumasi, Ghana Electricity Theft Detection by Monitoring of Consumption Data A presentation by Daniel Odoom(PG5080218) Project Supervised by Dr. Francis Effah Dr. Emmanuel Frimpong Kwame Nkrumah University of Science & Technology, Kumasi, Ghana PRESENTATION OUTLINE • • • • • • Background Problem Definition Aim and Objectives Methodology Anticipated Results Project Timelines 1 2 Background Developing countries, including Ghana, are grappling with a high rate of electricity theft which affects income of utility companies [1]. The infrastructure deployed by these utility companies to detect and control electricity theft has deficiencies which results in an immense loss of revenue [1]. A World Bank report in 2009 indicated that up to 50% of electricity in developing countries is acquired via energy theft [2]. www.knust.edu.gh 2 Background Cont’d An exercise conducted by the Electricity Company of Ghana (now Power Distribution Company) revealed that 11,890 out of 250,616 electricity meters inspected had been tampered with[11]. The main causes of electricity theft in Ghana include; • High electricity prices • Poor quality of power supplied • Collision between utility workers and consumers • Poor enforcement of the law against electricity theft and • PURC not fighting for the interest of consumers. Other factors are attitudinal, ignorance of the implication of stealing power, unemployment, and poverty [1]. www.knust.edu.gh 4 4 Background Cont’d Some of the most common methods used for stealing power include; • Bypassing the meter • Inverting the meter • Placing straps behind the meter • Switching meters etc. [5] Options put in place to combat this menace include; • Physical inspection • The use Smart Meters • Power theft control via plc system • Monitoring of consumer load profiles [7][9] www.knust.edu.gh 4 Problem definition Finding the gap…..

Objectives • To obtain consumer consumption data and segregate them into genuine consumer data and fraudulent consumer data • To develop a technique for detecting electricity theft • To compare developed technique to already existing approaches www.knust.edu.gh 6 Methodology • Outline activities to undertake to fit project plan • Comprehensive review of power theft detection techniques. www.knust.edu.gh 7 Project timeline www.knust.edu.gh 8 9 Anticipated Results Effective technique for detecting electricity theft www.knust.edu.gh 9 Reference [1] Yakubu, O., Babu, N.
