The Long-Term Development Planning of Energy Critical Infrastructures of Vietnam

Abstract

Renewable energy sources help increase the energy supply security and reduce greenhouse gas emissions in Vietnam. Highly variable and stochastic nature of renewable energy sources poses some challenges to study the problem of generation expansion planning for long-term perspective. The proposed multiobjective model for generation expansion planning considers the fuel restrictions on the power generation and transmission network to measure the geographical impact of the generation additions. Its objectives are minimization of investment, operation and transmission costs, environmental impact, imports of fuel and unmet demand cost Also the model takes into account the following types of constraints: flow balance constraints in the network with demand covering, power generation and transmission limit, generation and transmission investment, availability of local production of fossil fuels, system reliability requirements, maximum and minimum shares of RE resources, energy supply security requirements.
