2 Oman Energy & Water Conference



INTRODUCTION

Outcomes of this research project: 1) A laboratory-scale microgrid: Comprises of solar energy PV, wind energy conversion system, battery storage, data acquisition system, and power quality analysis device, connected to the local network (grid) along with a metering system. 2) A geographical information system (GIS) platform: live data from all components connected to the grid on a map 3) Conceptual Roadmap for Transition to Smart Grid: By considering: Experiences elsewhere, particularly from Australia; Interviewing stake holders (the ones who where available); Other studies.




DEFINITION

A smart grid consists of a power grid equipped with communications, controls, computers, SCADA, and other new technologies working together to respond to the integration of renewable energy sources to the grid, demand side management, automatic network reconfiguration, automatic supply restoration and in general respond to the continuous changes expected in the power grids of the future.




SMART DISTRIBUTION

1. Distribution Automation: Network automation and remote control. 2. Smart Aggregation: Aggregation of all sources, including distributed generators, and energy management on the distribution level. 3. Smart Metering: Smart metering infrastructure to facilitate consumer involvement in demand management.




RECOMMENDATIONS

Conceptual Roadmap for Transition to Smart Grid: By considering: Experiences elsewhere, particularly from Australia; Interviewing stake holders (the ones who where available); Other studies.


…



RECOMMENDATION

National Board/Committee/Panel/Authority: Form a national-level “Smart Grid Oman” as an

advocacy group for database development, knowledge transfer, industry-academia-government conversations and international networking;


1



RECOMMENDATION

Roadmap: Develop a ‘Smart Grid Roadmap’ for the

Electricity Sector in the Sultanate of Oman;


2



RECOMMENDATION

Grid-Connected PV Standard: Develop a grid-connected PV standard and

regulate/approve PV inverter brands that could be widely adopted without bureaucratic process;


3



RECOMMENDATION

Grid-Connected Roof-Top PV Implementation: implement a grid-connected residential and

commercial roof-top PV program: to reduce dependence on fossil fuel and arrest the peak demand through distributed renewable power generation;


4



RECOMMENDATION

Variable Tariff: Plan and implement cost-effective tariff; Target peak shifting;


5



RECOMMENDATION

AMI: Introduce the full Advanced Metering

Infrastructure (AMI) for real-time pricing for large customers;


6



RECOMMENDATION

Feeder trial for PV penetration: Plan a feeder trial for network performance

study as a basis for large-scale roof-top roll out; Accelerate the planned PV roll out;


7



RECOMMENDATION

Energy Efficiency Program: Introduce a national Energy Efficiency program

including an educational roll out, and introduce a star rating for electrical appliances as well as mandatory energy efficient/variable-speed motor-driven A/C for new installations;


8



RECOMMENDATION

Hybrid renewable energy systems: In RAECO, implement mandatory hybrid

renewable energy systems (PV-Diesel, Wind-Diesel, PV-Wind-diesel-battery, etc.);

Example: Set target to displace (for example) 50% diesel consumption within RAECO within the next five years;


9



RECOMMENDATION

Demand-Side Management: Develop a plan for Demand-Side Management

(DSM) using tools such as smart meters, energy efficiency, DG, and energy conservation program, etc., to reduce the need for new peaking units;


10



RECOMMENDATION

Network expansion for large-scale wind: OETC to work toward a strong link between

Dhofar Power System through Dukum to Main Integrated System to make provision for large-scale wind power generation in the Dhofar region and take advantage of the geographical diversity in peak demand;


11



RECOMMENDATION

National Interconnected Power System: OETC to work toward building a 400 kV national

interconnected bulk power system to benefit from the 400 kV planned GCC interconnection underpinning the current five-year statement;


12



RECOMMENDATION

Modern substations: Future 400 kV transmission substations are

preferred to be based on Gas-Insulated Switchgear (GIS) using digital protection, automation and control protocols, e.g., IEC61850;


13



RECOMMENDATION

Workforce program: The electricity sector to develop a workforce

modernization program to prepare for a futuristic power grid (targeted PD programs, Professional Masters, Master Classes, etc.);


14



RECOMMENDATION

Research program: Develop a cultural shift in research and

development engagement with research institutions and researchers for nurturing and developing national level expertise through international networks. To this end, a research gap analysis will be very useful.

MICROGRID TEST BED




MICROGRID PERFORMANCE TEST

Scenario 1; on-grid resistive load


Also, demonstrates transient operation




Scenario 2; on-grid, inductive load


Demonstrates heavy load and low-level wind generation




Scenario 3; Grid suddenly goes off


No wind, low-level solar (evening), grid goes off



GIS PLATFORM

On-Line monitoring of assets on a correct GIS-referenced location
