Key Drivers

1. Large amount of RES to

be installed in west of the

State

2. Weak existing

transmission network

3. Invest in the

transmission systems to

facilitate: Integration of

• Step 2 has been carried out on immediate basis since proposed assets have

relatively longer construction periods and immediate procurement decisions

are required in order to facilitate the planned RES integration by 2022

(concluded)

• Step 3 involves detailed analysis of the power system to characterise,

understand and define the diagnostic of the power system, find out

weakness and key operative and equipment (installation of Voltage

regulation devices etc.) needs. These equipments have shorter procurement

and installation periods (on-going)Outcome: Recommendations and guidelines for improvement of operation planning of the system with large RES

• Development of an integrated PSSE model of the Power system:

• Integration of RVPN and POSOCO models ;

• Integration of the proposed future facilities and demand 2021-22

• Execution of simulations and Analysis of results:

• Operative scenarios in different operative conditions (generation,

export, demand).

• Analysis of the performance of the facilities under the alternative

scenarios

Analysis: Scenario X
