The deterministic problem is formulated as follows: Objective function: (1) minimizes the investment cost for PV generation and battery capacity. And econdenotes the amount that the BSS can bear in the total cost for the installing BESS. Constraints: (2) represents the power. .
For the deterministic problem described in (1)–(16), hourly PV generation PV(t) and local demand PL(t) are uncertain parameters. It is a practical problem to determine the optimal PV and BESS mix that minimizes the. .
The proposed robust formulation for the optimal capacity planning has been transformed into an MILP formulation. The MILP is a deterministic optimization technique that can. [pdf]
