In mid-1985, Qualcomm was hired by to provide research and testing for a satellite network proposal to the (FCC). The following year, Qualcomm filed its first CDMA patent (No. 4,901,307). This patent established Qualcomm's overall approach to CDMA and later became one of the most frequently cited technical documents in history. The project with the FCC was scrapped in 1988, when the FCC told all twelve vendors that submitted proposals to form a j.

Spain's Royal Decree 917/2025, effective Nov. 16, 2025, reorganizes grid-access priorities by recognizing storage as a flexibility resource, grants renewables top dispatch rights, expands telemetry for storage and hybrids, and refines profitability rules. . In-Depth: Energy Regulation and Markets (formerly The Energy Regulation and Markets Review) offers an insightful survey of the key features of energy regulatory regimes worldwide, along with analysis of their impact on commercial practice. Focusing on the most consequential recent developments in. . Spain's Official State Gazette (BOE) today publishes the Royal Decree amending RD 413/2014, which updates the order of grid-access priority for electricity to boost the penetration of storage and flexible technologies. This regulation is structured around several key areas, including: greater control and planning by the National Commission for. . Electricity Regulation (EU) 2019/943 requires the European Network of Transmission System Operators for Electricity (ENTSO-E) to carry out the European resource adequacy assessments (ERAAs) on an annual basis. This move responds to the large-scale blackout incident experienced by the country in April this year.

Eastern Interconnection (EI) and Texas Interconnection (ERCOT) power grid models, this paper investigates the capabilities of using energy storage to improve frequency response under high PV penetration. . As renewable energy adoption accelerates globally, primary frequency regulation standards for energy storage power stations have become a cornerstone of grid reliability. Energy storage systems (ESS) play a critical role in balancing supply-demand mismatches caused by intermittent solar and wind. . Abstract— Frequency stability of power systems becomes more vulnerable with the increase of solar photovoltaic (PV). Energy storage provides an option to mitigate the impact of high PV penetration. However, they cannot sustain their output indefinitely. System operators have therefore. .
