Description
Summary:The key core contribution of the paper is to solve the problem of optimal sizing of hybrids systems with multiple storage facilities and minimizing the Levelised cost of electricity under the premise of ensuring the load supply. To achieve this, we have developed a new extended algorithm based on the Power Pinch Analysis (PPA) and the Modified Electric System Cascade Analysis (MESCA) which we previously used to size hybrid systems in previous papers [1,2]. Meanwhile, The ESCEA is used in the research to obtain the optimal combination of the contributions (%) of each type of generator adopted in an autonomous hybrid system (photovoltaic panels PV, wind turbines generators WT, and a concentrated solar power system CSP), with a thermal energy storage system (TES) to store heated fluid simultaneous with batteries for storing electrical energy (BESS). The ESCEA algorithm applied in a case study with data from the city of Oujda with an electrical load of 50 MWe indicated that it is possible to achieve 0.18 $/kWh of the Levelized Cost of Electricity (LCOE) for 0% Loss of Power Supply Probability (LPSP) with specific contributions of each generator type. •A new methodology for sizing hybrid systems with multiple storage systems.•Sizing of a hybrid CSP/PV/WT system with TES and batteries by the ESCEA.•Total Net Present Cost, LCOE and LPSP are the objective functions.•Case study for the city of Oujda in north-eastern Morocco.•Achieve the purpose of ensuring the load supply and minimizing the Cost.
