As for active distribution network（ADN） and consideration of the function of voltage transient drop compensation equipment and inverted distributed generation（DG）

the investment operation entity with consideration of distribution power supply operator as the investment operation entity of DG and the distribution network company as static synchronous compensator（STATCOM） to set up the bi-level planning model with the maximum operation profit of DG and the smallest cost of distribution company. The solution is made by the use of two level embedded cuckoo algorithms to obtain the optimal allocation plan. Finally

the analysis id made with IEEE 33 node voltage distribution system as an example to verify effectiveness and reasonableness of the proposed model and algorithm.
