Yearly investment to upgrade a distribution network has always been a key issue for a distribution network operator (DNO). Besides, new operational challenges are introduced to DNOs due to increasing photovoltaic (PV) generation. A high penetration of PV may cause voltage rise problem in a distribution network. This paper proposes a coordinated control strategy of Battery Energy Storage System (BESS)...
Battery energy storage systems (BESS) are expected to play an important part in future distribution networks. This paper analyses its impacts on the electricity demand profile through different scenarios of residential BESS uptake within the network serviced by a 33 kV/11 kV distribution substation in the state of Queensland, Australia. Two scenarios are considered: residential customers with rooftop...
Photovoltaic (PV) power is a favorable source of clean energy, which can be easily integrated into distribution systems, next to loads. However, to meet a considerable load portion of the system a high penetration level of PV is required. This high penetration level along with unbalanced connection of single phase rooftop PV units makes it necessary to assess the effect of PV on the voltage of unbalanced...
A price increase above competitive level is the consequence of market power manifestation. It makes some suppliers gain more profits and customers must pay more to buy electricity thus this reduces the efficiency of electricity market. This manuscript presents a briefly review of some international experiences on market power condition, and discusses strategic behaviour to exercise market power. To...
