Coalitional game theory to improve P2P trading in energy communities

An international research group has utilized a newly designed coalitional game system to ensure economic fairness between members of energy communities. The game system considers different types of prosumers relying on stand-alone and combinations of solar and storage.

Researchers propose new models for heat pump load forecasting in energy communities

Novel research from Germany and the USA has analyzed the impact of heat pump (HP) integration on the ability of day-ahead load forecasting in energy communities. Using different models, the scientists have also investigated whether HP loads should be forecasted separately from the rest of the household or both together.

Renewables must triple by 2030 to hit net-zero by 2050, says BloombergNEF

BloombergNEF says in a new report that solar and wind must drive most emissions cuts before 2030 to stay on track for net-zero by 2050. Its net-zero scenario targets a combined solar and wind capacity of 31 TW by 2050.

US government proposes 10 ‘national interest’ transmission corridors

Eight of the 10 transmission corridors proposed by the US Department of Energy (DoE) could facilitate transmission between grid regions. One would expand transmission within the Mid-Atlantic’s PJM grid region, and one would expand transmission in the Northern Plains.

Techno-economic feasibility of hydrogen storage in hydro-dominated countries

Scientists have investigated different techno-economic scenarios for using hydrogen storage in combination with hydropower and pumped hydro storage in Switzerland. They have found that hydrogen storage plays no major role under most conditions.

New PV system design strategy avoids oversizing, curtailment

A group of scientists in Thailand has outlined a new approach to avoid oversizing and overvoltage in energy markets applying volt-watt droop curtailment strategies. The novel methodology leads to a reduction in a PV system’s net present value but also increases its levelized cost of energy.

Renew Home launches virtual power plant solution

Renew Home, a partnership between Google Nest Renew and OhmConnect, aims to expand from 3 GW of electrical energy use to 50 GW by 2030.

India’s first utility-scale, standalone storage project gets regulatory nod

BSES Rajdhani Power’s new 20 MW/ 40 MWh project is India’s first utility-scale, standalone battery energy storage system to secure regulatory approval under Section 63 of the Indian Electricity Act, 2003. The project is supported by a concessional loan from the Global Energy Alliance for People and Planet (GEAPP).

Integrating pumped hydro with compressed air energy storage

A group of Chinese researchers has made a first attempt to integrate pumped hydro with compressed air storage and has found the latter may help the former to better deal with large head variations.

The impact of seasonal, meteorological factors on PV plant performance

Scientists in Japan have investigated the impact of seasonal, metereological factors on solar plant performance and have found the average power generation inefficiency reached significant levels. The findings suggest that optimal site for power plants requires careful consideration of meteorological and geographical data.
