In a standalone microgrid system, prolonging the life of the equipment is necessary to reduce the cost of its replacement. However, the size and installation costs of the storage systems must be appropriate. Therefore, this paper provides an appropriate weighting to minimize the cost of the microgrid system.
The DC components of the microgrid system consist of solar PV and WT, along with a battery energy storage unit (BESU). As for the AC components, the demand is met by local load, dump load, and DG acting as a backup power source. An energy management system (EMS) tracks and manages the power-sharing of each component of the MS.
The microgrid's energy flow is regulated by several modes, which operate according to a predetermined set of rules. In this study, the EMS is shown in the following modes: Mode 1: The energy generated by RES (such as PV and WT) adequately meets the load energy demand requirements.
A microgrid is a small power system constructed to manage Distributed Generators (DGs) from renewable energy and load clusters. The microgrid that connects to the bulk power system is called to be in “on-grid mode”, and when it disconnects from the bulk power system in an emergency, it is called to be in “islanded mode”.
Microgrid design will incorporate system cost. A reliable, cost-effective system is the goal. RES will dramatically lower microgrid running expenses. Energy storage systems also reduce load variability and improve system reliability. Table 4 Power-consuming devices needed by residential units. Annual load profile of the location under study.
