Abstract
This paper presents Security Constrained Economic Dispatch (SCED) of renewable energy systems (RES). Reformulation of SCED for RES comprising biomass, large and micro-hydro plants, solar PV, solar thermal, waste to energy plant, wind farm and geothermal has been carried out. This enables RES prime-moved power systems provide secure and reliable service. Each of these sources requires problem formulation and constraint handling mechanism that take into account security limits and credible contingencies. Modified IEEE 118 bus system (NREL-118 test system), Ethiopian renewable energy system, and modified New England 39-bus system with high RES penetration features were used as case studies. Modeling and simulation was conducted on MATLAB, MATLAB/MATPOER, and DIGSILENT power factory simulation platforms. According to the simulation results obtained, it is deduced that the economic dispatch of RES is a promising step in connection to developments needed in the adoption and realization of smarter grids.
