The future of the NPT: REVCON and beyond

The Treaty on the Nonproliferation of Nuclear Weapons (NPT), with its quinquennial review conferences (RevCons), has become the foundation of the international nonproliferation regime over the course of its 50-year history. With more states parties than any other arms control agreement (currently 191), the Treaty provides a legally binding framework for all states parties, constraining proliferation of nuclear weapons and committing the five recognized states who possess nuclear weapons to work toward disarmament. The NPT has enjoyed wide success in constraining the spread of nuclear weapons. Only one state party has left the agreement and gone on to acquire these weapons, and the overall track record of compliance with IAEA safeguards has been robust. However, for all its effectiveness in the area of nonproliferation, its achievements on the disarmament front have been relatively unimpressive. While the NWS – most notably the United States and the Soviet Union/Russia – have decreased the overall size of their nuclear arsenals significantly since 1970, these arsenals have remained an important feature of NWS security policies. The limited progress towards disarmament has created friction between the NNWS and NWS and has been the source of mounting tension within the NPT regime. The 2020 RevCon, the 50th anniversary of the NPT and 25th anniversary of its indefinite extension, faces a range of contentious challenges, old and new, which call into question the Treaty’s future viability.

STOCHASTIC OPTIMAL POWER FLOW FOR REAL-TIME MANAGEMENT OF DISTRIBUTED RENEWABLE GENERATION AND DEMAND RESPONSE (Final Report)

To meet the grand challenge of a sustainable energy future, there has been a surge of interest in renewable energy. Today, the uncertainty associated with renewable resources is handled by using operating reserves. The high penetration of renewable resources, however, introduces difficult-to-control dynamics and challenges for power system operation. Decision support tools are necessary at the bulk system operational level to recognize and efficiently utilize renewable resources and distributed demand response products in concert with traditional grid resources. It is envisaged that responsive load can potentially have very significant cost advantages over either spinning or non-spinning ramping reserve. Critical decisions are made during hour(s)-ahead and real-time power system operation regarding the commitment and dispatch of generators to ensure power delivery is both reliable and economic. These decisions are typically made by a security constrained optimal flow, which determines future generator commitments, dispatches, and ensures adequate reserves are available in the event of a contingency (unexpected outage) or if future system conditions deviate from forecasts. However, security has been always based on a pre-specified subset of contingency constraints whose enforcement does not guarantee security under all possible future possibilities while also giving little or no weight to the likelihood of each contingent event or the severity of its consequences. Existing tools, which are based exclusively on deterministic optimization models, do not yield optimal operational decisions to address these new challenges, in terms of both reliability and cost-effectiveness. This project has focused on developing a stochastic optimal power flow (SOPF) framework, which integrates renewable resource uncertainty, load uncertainty, distributed storage (DS), demand response (DR) products, in a holistic manner to address the uncertainty associated with ever-increasing renewable resources, along with the inclusion of distributed demand response products in future power systems. A proof-of-concept problem was created using the Pennsylvania-Jersey-Maryland (PJM) power system network. Synthetic wind generation was added to the system to simulate 50% wind penetration. A 1-hour test of SOPF operation indicated more than 6% operational cost savings. The project continued by adding the Midwestern Independent System Operator (MISO) as a partner, with focus shifting from SOPF to Stochastic Look-Ahead Unit Commitment (SLAC). Unlike PJM, MISO is faced with significant renewable energy resources within its footprint and is challenged with substantial uncertainty in its operations. The SLAC distinguishes itself from existing tools that operators use. At best, today’s tools solve two to three cases independently, where one or two system parameters, such as forecasted load level (e.g., a low, base, and high forecast), are varied and the resulting scenarios are analyzed independently. The stochastic-based optimization of SLAC leverages statistical information from an ensemble of potential operational scenarios and their respective likelihood. The SLAC output can be translated into valuable information to the operator such as suggested commitments, optimal scheduling and dispatch of resources, reserve requirements at both locational and zonal resolutions, ramping availability and requirements, availability of demand response including operational guidance concerning the near-term and real-time coordination between distributed energy resources, and utilization of distributed storage resources. The developed SOPF/SLAC tool, a stand-alone tool compatible with existing EMSs, will provide system operators with unprecedented visibility, flexibility and predictability to these resources and operational guidance concerning the real-time coordination between DERs and DR/DS products. The game changing and practical impact of this disruptive technology will be dramatic and will usher in a new era in the electric power industry, wherein green energy concepts are fully embraced, and electric power costs are lowered throughout the nation.

BAZAAR DIPLOMACY: Examining Iran's Nuclear Bargaining Tactics

Since undeclared elements of Iran’s nuclear program were revealed in 2002, Tehran has engaged in a decade of efforts to justify and advance its nuclear program. Unlike North Korea’s withdrawal from the Nuclear Nonproliferation Treaty (NPT), Iran has maximized advantage and minimized backlash by maneuvering near the borders of the NPT system. Iran has embraced a three-pronged approach to bargain with the international community: (1) divide international opposition, (2) delay international monitoring, negotiations, and sanctions, (3) and defy international monitoring, commitments, and pressure. Iran’s nuclear bargaining can be divided into several time periods, and Iran used divide, delay, and defy tactics in each period. During the first phase from 2003 to 2005, Iranian reformist leader Mohammad Khatami was more willing to negotiate with the international community, but his ability to negotiate was constrained domestically and particularly during his last year of leadership. Tehran mainly negotiated with the France, Germany, and the United Kingdom – the European 3 (EU-3) – to drive a wedge between European and U.S. pressures on Iran and to delay outside monitoring and prevent international sanctions. It is in this early period that Iran developed its range of divide, delay, and defy tactics. For divide, Iran negotiated with the EU-3 because Europe had a close and influential relationship with the United States, whereas other international actors such as Russia and China were powerful but could not form an united bloc against the U.S. Iran began to delay international monitoring of its nuclear program by creating hurdles for international inspectors, stalling requests for information, and not volunteering information but providing updates only when Iranian nuclear developments were exposed by other parties. Iranian diplomats also delayed negotiations and sanctions by framing talks, negotiating and responding slowly to offers, providing false hopes and the appearance of concessions before key international events and resolutions, and adopting temporary and shifting negotiating positions. To defy, Iran modified and razed nuclear sites to prevent detection, used legalistic and minimal interpretations to subvert commitments, argued for an international right to enrich uranium, and proclaimed a fatwa against nuclear weapons. After President Mahmoud Ahmadinejad came to power in 2005, Iran took a tougher stance internationally. Ahmadinejad and his cabinet did not provide major concessions to facilitate international negotiations, were less willing to seriously consider proposals to curb Iran’s nuclear program, and linked Iran’s nuclear program to sovereignty and national pride. Realizing that Europe was less optimistic about negotiations, Ahmadinejad leveraged Russia and China to Iran’s advantage. Both countries helped delay and dilute United Nations Security Council resolutions against Iran. Ahmadinejad employed more tactics to defy international monitoring and pressure. These tactics involved demonstrating Iran’s nuclear progress even as Tehran engaged in negotiations over its program. Iran also increased the cost of failed negotiations by sustaining and escalating regional and global tensions to coincide with international events and resolutions that criticized or condemned Iran’s nuclear program. The third and present phase of Iranian nuclear bargaining began during Ahmadinejad’s second term as president (2009-2012). During this period, Ahmadinejad’s power significant weakened and domestic turf wars made Iranian nuclear negotiations unpredictable and at times contradictory. Due to the domestic situation and the exhausting of successful divide and delay tactics, Iran began using more defy tactics. Iran, for example, considered enriching uranium to a higher percentage for naval reactors, warned of closing the Straits of Hormuz, and engaged in terrorist acts against the West and its allies. Currently, Iran’s range of bargaining options has narrowed, with many divide and delay tactics less useful since the international community has become more aware of Iranian efforts to stall and buy time. While Iran leaders have employed more acts of defiance, Iran’s ability to sustain its defy tactics are waning and it is still possible to prevent greater confrontation between Iran and the West.
