MEA has engaged the cross departmental collaboration and rapidly adjusting work patterns in accordance with technology in order to create new ideas or innovations for use in MEA which every working processes are carried out with transparency and efficiency. The progress of development of Smart Grid systems investment activities in 2021 are as follows:


    Monitoring & Control

    ·     Supervisory Control and Data Acquisition/Energy Management System / Distribution Management System (SCADA/EMS/ DMS)

    In 2020, MEA signed the contract of SCADA/EMS/DMS System Replacement Project, which has the modern technology for increasing the control capability of feeder in 12 kV and 24 kV. Furthermore, SCADA/EMS/DMS System makes more efficient control of the system and fixing power outages. There are functions for this system as the following:

    1. Real-Time Network Analysis

    The Network Analysis functions execute in a sequence referred to as the Real-Time Sequence (RTS). The RTS results allow the user to visualize the current state of the power system, the potential effect of contingencies, and thereby determine if corrective or preventive control action is necessary.

    The real-time Network Analysis functions are named as follows, where they are listed in the order in which they normally execute as a part of the RTS: Real-Time Model Update (MU), State Estimator (SE), Bus Load Forecast (BLF), Network Parameter Adaptation (NPA) and Security Analysis (SA)

    2. System Load Forecast (SLF)

    The System Load Forecast (SLF) function is based on a short-term load forecast model to forecast the total power system load for a variable period from the time of the forecast request. These loads correspond to the HV and MV loads served by the power system network with in all service areas. The load values from SLF are capable of being used to support the Network Analysis functions such as Bus Load Forecast.

    3. State Estimator (SE)

    The State Estimator (SE) function provides consistent, updated, reliable, and most probable power flow solutions of the HV/MV power system using the current network model of the power system along with real-time status and analog measurements, forecasted and scheduled values, and user entries, which for the MV network is based on an unbalanced three-phase model. Solutions for all observable and unobservable portions of the power system are provided. 

    4. Network Parameter Adaptation (NPA)

    The Network Parameter Adaptation (NPA) function provides and maintain parameters that are not directly monitored.

    The forecasting parameters are adapted from the following information sources:

    ·       State Estimator solutions

    ·       Circuit breaker status time and/or load dependencies

    ·       Statistics of monitored real-time parameters

    ·       Bus Load Forecast solutions 

    ·       System Load Forecast solutions

    ·       User adjusted parameters via an interface that allows the on-line tuning of power system results by making changes to network characteristics such as those associated with lines and transformers

    5. Security Analysis

    Security Analysis (SA) function is used to assess the security of the HV power system under specified contingency conditions. Security Analysis provides the capability to evaluate a contingency involving increase or loss of generation or increase or loss of load by generation reallocation in the external network.

    Fault Location, Isolation, and System Restoration

    The objective of the Fault Location, Isolation, and System Restoration (FLISR) application is to improve customer service by minimizing the duration and extent of forced outages due to real-time faults directly affecting the MV power system network. Whenever sustained faults are detected by FLISR, the Dispatchers are notified by a special FLISR “alarm” indication and, upon acknowledgement, taken directly to that part of a schematic or geographical world-map display where the fault has occurred and where the results of any FLISR actions as well as the fault information reported by FRTUs (such as fault current direction) can be viewed. Furthermore, the Dispatchers are able to quickly navigate from this display to the display where the FLISR recommendations can be viewed.
