The strategic positioning and appropriate sizing of Distributed Generation (DG) and Battery Energy Storage Systems (BESS) within a DC delivery network are crucial factors
Battery energy storage systems (BESS) are integrated with renewable distribution generators (DG) within the distribution network (DN) to mitigate active power loss and improve the bus voltage profile through optimal placement and sizing. This work identifies the optimal location for BESS and DGs placement by deriving a loss sensitivity factor by
The distributed generation system must have a number of specific features, such as an isolating switch or circuit breaker that the distribution company''s service teams can access to disconnect the DG system from the lines. The system also needs a meter that separately measures the energy imported and exported.
Presently, substantial research efforts are focused on the strategic positioning and dimensions of DG and energy reservoirs. Ref.

The general optimization objective is to define the best DG mix and energy storage units for self-sufficient micro energy grids. A multi-objective genetic algorithm (GA) was applied to solve the planning problem at a minimum optimization goal of overall cost (including investment cost, operation and maintenance cost, and fuel cost) and carbon
When assessing the use of energy storage to reduce fuel consumption from associated DG, the cost function should include generator fuel consumption as this is the main operational cost. This necessitates that constraints should be added to reflect fuel consumption with the power output of the generator(s).
