First, each customer individ- ually determines the optimal size and initial scheduling of ESS to be installed in parallel with PV over a day- ahead planning horizon. The objective of installing ESS is to reduce the electricity bill while minimizing ESS aging effect. Then, after the day-ahead planning, customers man- age their system in a near real-time fashion to account for voltage conditions in order to avoid voltage-rise-associated curtailments. Customers along the feeder communicate with each other and exchange information about voltage devi- ation at their nodes in order to reach a consensus about average voltage situation in the distribution network. Based on voltage situation, EMS updates the lower bound on net power exchange with the grid for the hour ahead. Also, an iterative method is proposed to determine the lifetime of ESS and the economic benefits gained over the life- time. Simulation results for IEEE 33-bus test system prove the effectiveness of the proposed EMS and its financial viability.
