A small scale, RESs and BESSs can be iden i ied as Dis ibu ed En-

The op imal dispa ching o he uni s composing a MG is de ined by

A la ge po ion o he s udies p esen in he li e a u e models he MG

applica ion o single busba model implies ha all he powe lows

Among he s udies p esen in he li e a u e, [26] p oposes an EMS o

he aim o minimizing cos s and emissions. In [27] and [28] he au ho s

[29] p opose an op imal managemen s a egy o a mul i-ene gy MG

a lowe laye made o single mul i-ene gy MGs and wi h an uppe laye
ha coo dina es he MGs, applying a dynamic p ice mechanism, and
ha is in e aced wi h he dis ibu ion ne wo k. Ne e heless, a single

eac i e powe is neglec ed. A me hodology o op imally ope a e a BESS,

pu pose o he s udy is o y o employ he BESS as he unique lexible

MG is modelled as a single busba sys em and eac i e powe is
neglec ed.
O he s udies apply a mul i-busba model o MGs, o adhe e o eali y
in a be e way. Fo example, in [31] an EMS o a MG eeding esi-
den ial, comme cial and indus ial use s wi h PV, WT and BESS uni s is

Howe e , he managemen o BESS does no conside he ela ionship
