Abstract
Security constrained multi area multi objective dynamic economic dispatch (SCMAMODED) with renewable energy (RE) and all the possible MTDC stability constraints is formulated for the first time. The stability merits of multi terminal DC (MTDC) tie lines as compared to the traditional HVAC forms the main objective of this paper. Probabilistic load flow (PLF) is applied to determine the system parameters while the uncertainties are modelled using Scenario Based Method (SBM). The simulation results reveal that with the use of MTDC tie lines, the frequency and voltage stability in the MAMODED with renewable energy sources (RES) are enhanced while keeping the MTDC power exchange interface nodes at secure levels.

Summary
Multi area stability is the continuance of intact operation of an interconnected system following a disturbance. This paper is concerned with stability studies in a multi area system with increased renewable energy (RE) penetration levels. Three recent works have considered multi area economic dispatch (MAED) with renewable energy (RE). In [1], a multi area multi objective dynamic economic dispatch (MAMODED) for a retailer, a model taking into account hydrothermal, wind and a power reserve market is proposed. Scenario-based method (SBM) is adopted for uncertainty
