The present invention relates to a computer-implemented method of providing technical sizing parameters for an energy supply system supplying electrical energy to an installation connected to a public grid subject to potential service interruptions, said computer-implemented method comprising the steps of: ⋅entering electricity consumption chronology (S1) of said installation; ⋅entering photovoltaic production capacity limits and energy storage unit capacity limits (S9); ⋅estimating a ratio (S11) of self-sufficiency or of self-consumption, or of internal rate of return; ⋅displaying (S13) a plurality of energy supply system configurations on user interface means; wherein each configuration is associated to a sensitivity parameter, said sensitivity parameter enabling to determine the optimized technical sizing parameters of the energy supply system regarding the reliability of the public grid. The present invention further relates to a computer program product aimed at being executed on a computer system to implement this computer-implemented method.
A computer-implemented method of providing technical sizing parameters for an energy supply system (100) on an existing support structure (3) having a predetermined available surface to be equipped with photovoltaic modules (102), said energy supply system (100) comprising at least:
The method according to any one of the preceding claims, wherein the method (1) further comprises a step of entering technical parameters of the energy storage unit (S8′), said step (S8′) being performed before the step of entering production capacity limits and energy storage capacity limits (S9).
The method according to any one of the preceding claims, wherein the database (53) is in communication with a sizing model (55) able to estimate the technical sizing parameters of the energy supply system (100) based on the entry parameters.
The method according to any one of the preceding claims, wherein it further comprises a step of computing a cost model (S12), said step of computing a cost model (S12) being performed just before the step of displaying (S13) a plurality of energy supply system configurations to ensure an optimal energy supply system design, said cost model taking into account the energy supply system configuration chosen, the photovoltaic production capacity limits, the energy storage unit capacity limits, and the aging devaluation of the energy supply system configuration.
The method according to any one of the preceding claims, wherein it further comprises a step of storing (S14) the computed data into the database (53) for a further installation, said step of storing (S14) the computed data being performed after the step of displaying (SI 3) a plurality of energy supply system configurations.
The method according to any one of the preceding claims, wherein the sensitivity parameter is further based on a capital expenditure of said energy supply system (100).
The method according to any one of the preceding claims, wherein the sensitivity parameter further takes into account the cost of the public grid electricity.
The method according to any one of the preceding claims, wherein it computes and displays on the user interface means (51) power of the photovoltaic electricity generation unit (101).
The method according to any one of the preceding claims, wherein it further computes and displays on the user interface means (53) sizes of modules constituting the energy storage unit (103).
A computer program product for providing technical sizing parameters for an energy supply system (100) on an existing support structure (3) having a predetermined available surface to be equipped with photovoltaic modules (102), said energy supply system (100) comprising at least
