Based on a reliable prediction method, this paper proposes a dynamic evolutionary frame in order to maximize the economic benefits for micro-grid (MG) over time. The optimal solution is a series of time related control vectors for the whole time span, which can control the energy storage to charge and discharge optimally by the appropriate energy quantity and at the appropriate time instants. The...
Linear programming (LP) is used to calculate the sizes of the components of a hybrid renewable energy system (HRES) that minimize the present worth of capital and operating costs. The constraints are the energy demand, emissions from the diesel engine, satisfying battery autonomy hours, maintaining system reliability, and keeping a limit on the renewable energy resources. Such formulation uses assumed...
This paper proposes a fuzzy linear programming (LP) based solution approach for the long term multistages best generation mix (BGM) problem considering wind turbine generators (WTG) and solar cell generators (SCG), and CO2 emissions constraints. The proposed method uses fuzzy set theory to consider the uncertain circumstances ambiguities associated with budgets and reliability criterion level. The...
